(3) Operation by external event count input (TIAm0)
External event count input
(a) Operation
TAAmCCR0 register
TAAmCCR1 register
To count the 16-bit counter at the valid edge of the external event count input (TIAm0) in the interval timer
mode, the 16-bit counter is cleared from FFFFH to 0000H by the valid edge of the external event count
after the TAAmCE bit is set from 0 to 1.
When 0001H is set to both the TAAmCCR0 and TAAmCCR1 registers, the TOAm1 pin output is inverted
each time the 16-bit counter counts twice.
The TAAmCTL1.TAAmEEE bit can be set to 1 in the interval timer mode only when the timer output
(TOAm1) is used with the external event count input.
