(2) Interval timer mode operation timing
(a) Operation if TTnCCR0 register is set to 0000H
(b) Operation if TTnCCR0 register is set to FFFFH
INTTTEQCn0 signal
If the TTnCCR0 register is set to 0000H, the INTTTEQCn0 signal is generated at each count clock, and
the output of the TOTm0 pin is inverted.
The value of the 16-bit counter is always 0000H.
Remark
If the TTnCCR0 register is set to FFFFH, the 16-bit counter counts up to FFFFH. The counter is cleared to
0000H in synchronization with the next count-up timing. The INTTTEQCn0 signal is generated and the
output of the TOTm0 pin is inverted. At this time, an overflow interrupt request signal (INTTTIOVn) is not
generated, nor is the overflow flag (TTnOPT0.TTnOVF bit) set to 1.
