matches TA0REG, though the up-counter UC0 is not cleared.
comparator pulse on which the values in the up counter UC1 and TA1REG match. When
the match detect signal is output simultaneously from both the comparator TMRA0 and
TMRA1, the up counters UC0 and UC1 are cleared to 0 and the interrupt INTTA1 is
generated. Also, if inversion is enabled, the value of the timer flip-flop TA1FF is inverted.
(3) 8-bit PPG (Programmable pulse generation) output mode
The comparator match signal is output from TMRA0 each time the up counter UC0
In the case of the TMRA1 comparator, the match detect signal is output on each
The output pulses may be active-low or active-high. In this mode TMRA1 cannot be
used.
Example: When TA1REG = 04H and TA0REG = 80H
<TA1FFC1:0> = “10”
<TA1FFC1:0> = “01”
Example: <TA1FFC1:0> = “01”

TA1OUT
Square wave pulses can be generated at any frequency and duty ratio by TMRA0.
TMRA0 outputs pulses on the TA1OUT pin (Shared with PC1).
