Example: To generate an INTTA1 interrupt every 12 µs at fc = 27 MHz, set each
The input clocks for TMRA0 and TMRA1 are different from as follows.
TMRA0: TA0IN input, φ T1, φ T4 or φ T16
TMRA1: Match output of TMRA0, φ T1, φ T16, φ T256
Both TMRA0 and TMRA1 can be used independently as 8-bit interval timers.
Setting its function or counter data for TMRA0 and TMRA1 after stop these
Generating interrupts at a fixed interval (Using TMRA1)
TMRA1 then set the operation mode, input clock and a cycle to TA01MOD and
TA1REG register, respectively. Then, enable the interrupt INTTA1 and start
TMRA1 counting.

Stop TMRA1 and clear it to 0.
Select 8-bit timer mode and select φ T1 (0.3 µ s at fc = 27
MHz) as the input clock.
Set TA1REG to 12 µ s ÷ φ T1 = 40 = 28H
Enable INTTA1 and set it to level 5.
Start TMRA1 counting.
