POFSi = 0
POFSi = 1
IR bit
in TAiIC register
Low-level output
at count stop
Output reversed at underflow
High-level output
at count stop
Low-level output
when the TAiS
bit is 0.
High-level output
when the TAiS
bit is 0.
Output reversed
at underflow
Set to 0 by an interrupt request acknowledgement or by a program.
i = 0 to 4
POFSi : Bits in the TAPOFS register
The above timing diagram applies when the register bits are set as follows:
- The MR0 bit in the TAiMR register
= 1 (pulse output)
- Bits MR2 to MR1 in the TAiMR register = 10b (counts while a low-level signal is applied to the TAiIN pin)
- Value in the TAi register (n)
= 0004h
