Example: To generate an INTTA1 interrupt every 20 us at f
X: Don't Care, −: No change
Note: The input clocks for TMRA0 and TMRA1 are different from as follows.
TA01RUN
TA01MOD
TA1REG
INTETA1
TA01RUN
Operation in Each Mode
(1)
TMRA0: TA0IN input, φT1, φT4 or φT16.
TMRA1: Matches output of TMRA0, φT1, φT16, and φT256.
a. Generating interrupts at a fixed interval (Using TMRA1)
Both TMRA0 and TMRA1 can be used independently as 8-bit interval timers.
Select the input clock using Table 3.12.2.
8-bit timer mode
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 φT1 (0.16 μs at f
50 MHz) as the input clock.
Set TA1REG to 20 μs ÷ φT1 = 125(7DH)
Enable INTTA1 and set it to level 5.
Start TMRA1 counting.
