PA6).
the 8-bit up-counter UC0 matches the timer registers TA0REG and TA1REG.
the up-counter UC1 of TMRA1 cannot be used in this mode, TA01RUN<TA1RUN> must be set to 1
to enable TMRA1 counting.
TA01RUN<TA0RDE>
A square wave of any frequency with any duty cycle can be output using TMRA0. Either
TMRA1 cannot be used in this mode. The square wave is forwarded to TA1OUT (shared with
This mode is used to output a programmable square wave by inverting the timer output every time
However, the condition (TA0REG set value) < (TA1REG set value) must be satisfied. Although
Figure 3.9.19 shows a block diagram of 8-bit PPG output mode.
