ARCHITECTURE
The KT KS are new members of the MCS-96 family
having the same architecture and use the same in-
struction set as the 80C196KB Many new features
have been added including
CPU FEATURES
Y Powerdown and Idle Modes
Y 16 MHz Operating Frequency
Y A High Performance Peripheral
Transaction Server (PTS)
Y 37 Interrupt Vectors
Y Up to 512 Bytes of Additional Code
RAM
Y Up to 1 Kbyte of Additional Register
RAM
Y ‘‘Windowing’’ Allows 8-Bit Addressing
to some 16-Bit Addresses
Y 1 75 ms 16 x 16 Multiply
Y 3 ms 32 16 Divide
Y Oscillator Fail Detect Circuitry
PERIPHERAL FEATURES
Programmable A D Conversion and S H Times
10 Capture Compare I O with 2 Flexible Timers
(250 ns Resolution and Double Buffered Inputs)
Synchronous Serial I O Port for Full Duplex Seri-
al I O
Synchronous Asynchronous Serial I O Port
(with Dedicated 16-Bit Baud Rate Generator)
Total Utilization of ALL Available Pins (I O Mux’d
with Control)
(2) 16-Bit Timers with Prescale Cascading and
Quadrature Counting Capabilities
Up to 12 Externally Triggered Interrupts
NEW INSTRUCTIONS
XCH XCHB Exchange the contents of two loca-
tions either Word or Byte is support-
ed
BMOVI
Interruptable Block Move Instruction
allows the user to be interrupted dur-
ing long executing Block Moves
TIJMP
Table Indirect JUMP This instruction
incorportes a way to do complex
CASE level branches through one in-
struction An example of such code
savings several interrupt sources and
only one interrupt vector The TIJMP
instruction will sort through the sourc-
es and branch to the appropriate sub-
code level in one instruction This in-
struction was added especially for the
EPA structure but has other code sav-
ing advantages
EPTS DPTS Enable and Disable Interrupts (Works
like EI and DI)
SFR OPERATION
A total of 1 Kbyte of Register RAM is implemented
on the 87C196KT KS devices These locations sup-
port the on-chip peripherals that the 87C196KT KS
has (SFR’s) as well as offering a data storage area
These locations are all 8-bit directly addressable by
use of the windowing technique Any 32- 64- or 128-
byte section can be relocated into the upper 32- 64-
or 128-byte area of the Register RAM area 080H –
0FFH
