13.3 8-bit Compare Output (16-bit)
TheMC80F0104/0204 has Timer Compare Output func-
tion. To pulse out, the timer match can goes to port pin(
T0O or T2O) as shown in Figure 13-3 or Figure 13-4 .
Thus, pulse out is generated by the timer match. These op-
eration is implemented to pin, R05/AN5//T0O/TXD or
R06/AN6/T2O/ACK.
In this mode, the bit T0OE or T2OE bit of Port Selection
register1 (PSR1.0 or PSR1.1) should be set to "1". This pin
output the signal having a 50 : 50 duty square wave, and
output frequency is same as below equation.

13.4 8-bit Capture Mode
The Timer 0 capture mode is set by bit CAP0 of timer
mode register TM0 (bit CAP1 of timer mode register TM1
for Timer 1) as shown in Figure 13-11 . Likewise, the Tim-
er 2 capture mode is set by bit CAP2 of timer mode register
TM2 (bit CAP3 of timer mode register TM3 for Timer 3)
as shown in Figure 13-12 .
