setting is specified by the value set in TA01MOD<TA01CLK1:0>.
the overflow output from UC0 is used as the input clock. In any mode other than
16-bit timer mode, the input clock is selectable and can either be one of the internal
clocks φT1, φT16 or φT256, or the comparator output (The match detection signal)
from TMRA0.
<TA0RUN> and TA01RUN<TA1RUN> can be used to stop and clear the up
counters and to control their count. A reset clears both up counters, stopping the
timers.
Prescaler
A 9-bit prescaler generates the input clock to TMRA01.The clock φT0TMR is
The prescaler operation can be controlled using TA01RUN<TA0PRUN> in the

These are 8-bit binary counters which count up the input clock pulses for the
