X: Don’t care, −: No change
Note: The input clocks for TMRA0 and TMRA1 are different from as follows.
TA01RUN
TA01MOD
TA1REG
INTETA01
TA01RUN
Operation in Each Mode
(1) 8-bit timer mode
Example: To generate an INTTA1 interrupt every 8.0 μs at fc = 36 MHz, set each register
a. Generating interrupts at a fixed interval (Using TMRA1)
Setting its function or counter data for TMRA0 and TMRA1 after stop these registers.
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.
TMRA0: TA0IN input, φT1, φT4 or φT16
TMRA1: Match output of TMRA0, φT1, φT16, φT256
Both TMRA0 and TMRA1 can be used independently as 8-bit interval timers.
To generate interrupts at constant intervals using TMRA1 (INTTA1), first stop
Select the input clock using Table 3.7 2.
