Basic timing of operation in interval timer mode
When the TPnCE bit is set to 1, the value of the 16-bit counter is cleared from
FFFFH to 0000H in synchronization with the count clock, and the counter
starts counting. At this time, the output of the TOPn0 pin is inverted.
Additionally, the set value of the TPnCCR0 register is transferred to the CCR0
buffer register.
When the count value of the 16-bit counter matches the value of the CCR0
buffer register, the 16-bit counter is cleared to 0000H, the output of the TOPn0
pin is inverted, and a compare match interrupt request signal (INTTPnCC0) is
generated.
The interval can be calculated by the following expression.
