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
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
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
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
The special functions of the pins are selected in the
Port 7 SFRs The Port 2 I O Port section of the
8XC196MC User’s Manual can be referenced when
setting up the Port 7 SFRs Port 7 SFRs are located
in the following locations
