HSP45116-DB

The current port and HSP-EVAL address are changed by

opening up the Port Configuration Window, using the up/down

arrow keys to select the desired parameter, and toggling the

space bar to change the selection. Proper operation of the

control panel software requires that the HSP-EVAL Board

address specified in the port configuration window matches

the address jumpered in the Address Selection Section of the

HSP-EVAL’s J4 jumper field (see HSP-EVAL User’s Manual).

Clock Select

The Clock Select portion of the control panel is used to tell

the Control Panel software which of four different clock

sources is being supplied to the HSP45116-DB. The choices

include one of two different software generated clocks

(Manual CLK or Port CLK), an oscillator clock provided by

the HSP-EVAL (OSC. CLK), or an externally supplied clock

(External CLK). The clock mode selected must be consistent

with the Clock Select jumper position in the HSP-EVAL’s J4

jumper field. If either Manual CLK or Port CLK are specified

in the Control Panel, the clock select jumper must be

inserted in the CTL0 position. If either OSC. CLK or External

CLK is specified, the jumper must be inserted at the

OSC_CLK or EXT_CLK position respectively.

In Manual CLK mode, single clock pulses are sent to the

HSP45116 by depressing the F2 function key. The clock

pulse is software generated by setting and clearing the CTL0

bit of the CTL Control Register on the HSP-EVAL. After each

clock, the HSP45116-DB's RO0-15 and IO0-15 outputs are

serialized and read into the PC for display in the Control

Panel. In this mode, file input and output is supported (see

File I/O Select Section).

In Port CLK mode, a free running clock is sent to the

HSP45116 by depressing the F2 function key. The clock

pulses are software generated by continually setting and

clearing the CTL0 bit of the CTL0-15 Register on the HSP-

EVAL. After each clock the HSP45116-DB's RO0-15 and

IO0-15 outputs are serialized and read into the PC for

display in the Control Panel. In this mode, file input and

output is supported (See File I/O Select Section).

In OSC. CLK mode, the HSP45116 is supplied with a clock

by the oscillator on-board the HSP-EVAL. In this mode, the

Control Panel can be used for modifying the various control

signal states, the configuration registers, and the complex

inputs to the NCOM. However, the software is unable to

provide file based I/O to the evaluation board set since the

data rate required by the oscillator clock is orders of

magnitude greater than that possible through the parallel

port of the PC. As a result, the Control Panel disables file

based I/O and the display of NCOM output in this mode.

In External CLK mode, the HSP45116 is supplied with a

clock through the 96-Pin DIN connector P1 on the HSP-

EVAL. In this mode, the Control Panel can be used for

modifying control signal states, the various configuration

registers, and the complex inputs to the NCOM. However,

the software does not support file based I/O to the evaluation

board set since the data rate required may be much greater

than that capable through the parallel port of the PC. In this

mode, the Control Panel disables file based I/O and the

display of NCOM output.

The clocking mode used by the control panel is indicated by

the position of the “check mark” symbol within the Clock

Select portion of the Control Panel. A different clocking

mode may be selected by positioning the “check mark”

symbol in front of the desired clocking mode. The position of

the “check mark” is changed by using the cursor keys to

move the active window to the desired position and then

toggling the space bar to move the “check mark”.

File I/O Select

The File I/O Select portion of the Control Panel allows the

user to specify files which can be used as an input data

source or an output data sink for the HSP45116-DB. If file

based input is selected, Control Panel software down loads

data from the specified file to registers on the HSP-EVAL

and clocks the data into the RIN0-15 and IMIN0-15 inputs of

the HSP45116. If file based output is specified, the software

reads the data on the RO0-15 and IO0-15 outputs of the

HSP45116 via the HSP-EVAL’s output shift register and

stores the data in the specified file. The input data is loaded

on to the input busses prior to the software generated clock

and the output data is read from the output busses following

the software generated clock.

File based I/O is activated by using the space bar to toggle

the “check mark” symbol in the window proceeding the Input

and Output File identifier in the Control Panel's File I/O

Section. If either file input or output is activated, the

respective file name must be entered in the window to the

right of the I/O file identifier. File input or output may be

disabled at any time by toggling the respective “check mark”.

Note: file I/O is only valid when either the ‘Manual CLK’

or ‘Port CLK’ clocking modes are selected and it is

disabled if other clocking modes are specified.

The input and output data files are ASCII based and have a

format as described in Appendix A. There is no limitation to

the input and output file size, and care must be taken if file

output is specified since data is collected in the file until file

output is deactivated or the NCOMCTRL Program is exited.

HSP45116 Complex Data Inputs

The data windows to the left of the HSP45116 icon are used

to specify hexadecimal values which drive the part's complex

inputs, RIN0-15 and IMIN0-15. Data entered into these

windows is down loaded to registers on the HSP-EVAL

which drive the HSP45116-DB's complex input busses.

Note: Jumpers must be inserted into the OE_BUS1 and

OE_BUS2 positions of the HSP-EVAL's J4 jumper field

to enable the register outputs containing the complex

data.
