ARINC 429 Transmitter / Dual Receiver for 8-Bit Bus

Holt Integrated Circuits 

HI-6011

Write to HI-6011: (CS = 0, WR = 0)

Write Receiver 1 ID Label Register.

The Receiver ID Label Register bits are written in the same way as outlined in Table 2 for read/write

cycle 1. Two modes of operation are possible for the label ID.

Mode 0: Mode 0 is enabled by writing all zeros to the Receiver ID Label Register. In this mode, any ID

001 label is accepted and the most recent word overwrites unread previously received word.

Mode 1: Mode 1 is enabled when any non-zero value is written to the Receiver ID Label Register.

In this mode, only received labels matching the written ID label are responded to. The first word in is

retained forever until read or until receiver 2 is reset. Any ID label write (same data or different) causes

receiver 1 to reset.

See Section “Receiver Operation” for further information.

Write Receiver 2 ID Label Register.

010

Same operation as Receiver 1 above.

011 Write Control Word Register. See Section “Control Word Register”.

Master Reset.

Resets the chip, irrespective of data. Ceases all transmission; re-initializes receivers. Does not change

setup parameters.

1xx Note: A reset to the receivers or a master reset should be given following a change to data rate, parity

or input clock specification.

A hardware function RST is provided which performs the same functions as the software controlled

reset.
