The 8XC196MD is a 16-bit microcontroller designed primarily to control 3 phase AC induction and DC brush-
less motors The 8XC196MD is based on Intel’s MCS 96 16-bit microcontroller architecture and is manufac-
tured with Intel’s CHMOS process
The 8XC196MD has a three phase waveform generator specifically designed for use in ‘‘Inverter’’ motor
control applications This peripheral allows for pulse width modulation three phase sine wave generation with
minimal CPU intervention It generates 3 complementary non-overlapping PWM pulses with resolutions of
0 125 ms (edge trigger) or 0 250 ms (centered)
The 8XC196MD has 16 Kbytes on-chip OTPROM ROM and 488 bytes of on-chip RAM It is available in two
packages PLCC (84-L) and EIAJ QFP (80-L)
Operational characteristics are guaranteed over the temperature range of b40 C to a85 C
The 87C196MD contains 16 Kbytes on-chip OTPROM The 83C196MD contains 16 Kbytes on-chip ROM All
references to the 80C196MD also refers to the 83C196MD and 87C196MD unless noted
OTPROM (One Time Programmable Read Only Memory) is the same as EPROM but it comes in an unwindowed package
and cannot be erased It is user programmable

Interrupt and PTS Vectors
The 8XC196MD has three new interrupt and PTS
vectors which are Capture Compare5 Compare 4
and Capture Compare4 Table 3 shows these inter-
rupt vectors and priorities These are shown as re-
served vectors in the 8XC196MC User’s Manual
Frequency Generator
The Frequency Generator (FG) Peripheral which
was not available on the 8XC196MC device is avail-
able on the 8XC196MD device The FG outputs a
programmable-frequency 50% duty cycle waveform
on the FREQOUT pin (P7 7) There are two 8-bit reg-
isters which control the FG peripheral
Frequency Generator Control Register
(FG CON) at 1FB8h
Frequency Generator Period Count Register
(FG COUNT) at 1FBAh
The FG CON can be read or written This register
is loaded with a value which determines the number
of counts necessary for toggling the output The fol-
lowing equation should be used to calculate the
FG CON value
FG CON value e
FXTAL
b1
16 (FG Frequency)
where FG Frequency is from 4 kHz to 1 MHz
The FG COUNT is loaded with the FG CON reg-
ister value The FG COUNT register is decrement-
ed every eighth state time When it reaches 00h the
FG COUNT register will send a signal to toggle the
output pin and reload the FG COUNT register with
the value in the FG CON register The
FG COUNT can only be read not written
The FREQOUT pin (P7 7) must be configured for a
special function to use it for the Frequency Genera-
tor feature
Port 7
Port 7 is an additional bidirectional port that was not
available on the 8XC196MC device Port 7 can be
used as I O or some of the pins have special func-
tions The pins are listed below followed by their
special functions

setting up the Port 7 SFRs Port 7 SFRs are located
in the following locations

PIN DESCRIPTIONS (Alphabetically Ordered) (Continued)
Symbol
Function
PALE
(P2 1)
A falling edge in Slave Programming Mode and Auto Configuration Byte
Programming Mode indicates that ports 3 and 4 contain valid programming
address command information (input to slave)
PROG
(P2 2)
A falling edge in Slave Programming Mode begins programming A rising edge
ends programming
PVER
(P2 0)
A high signal in Slave Programming Mode and Auto Configuration Byte
Programming Mode indicates the byte programmed correctly
CPVER
(P2 6)
Cumulative Program Verification Pin is high if all locations since entering a
programming mode have programmed correctly
AINC
(P2 4)
Auto Increment Active low input enables the auto increment mode Auto
increment will allow reading or writing of sequential EPROM locations without
address transactions across the PBUS for each read or write
