(2) Operation timing in external event count mode
Caution In the external event count mode, use of the timer output (TOAm0, TOAm1) is disabled. If
(a) Operation if TAAmCCR0 register is set to 0000H
When the TAAmCCR0 register is set to 0000H, the 16-bit counter is repeatedly cleared to 0000H and
generates the INTTAmCC0 signal each time it has detected the valid edge of the external event count
signal and its value has matched that of the CCR0 buffer register.
The value of the 16-bit counter is always 0000H.
Remark
TAAmCCR0 register
using timer output (TOAm1) with external event count input (TIAm0), set the interval timer
mode, and select the operation enabled by the external event count input for the count clock
(TAAmCTL1.TAAmEEE bit = 1) (see 6.6.1 (3)
(TIAm0)).
