with the count clock, and the counter starts counting. At this time, the output of the TIOPn0 pin is inverted.
Additionally, the set value of the TPnCCR0 register is transferred to the CCR0 buffer register.
cleared to 0000H, the output of the TIOPn0 pin is inverted, and a compare match interrupt request signal
(INTTPnCC0) is generated.
TPnCTL0
TPnCTL1
When the TPnCE bit is set to 1, the value of the 16-bit counter is cleared from FFFFH to 0000H in synchronization
When the count value of the 16-bit counter matches the value of the CCR0 buffer register, the 16-bit counter is
The interval can be calculated by the following expression.
Interval = (Set value of TPnCCR0 register + 1)

This bit can be set to 1 only when the interrupt request signals (INTTPnCC0 and INTTPnCC1)
are masked by the interrupt mask flags (TPnCCMK0 and TPnCCMK1) and timer output (TIOPn1)
is performed at the same time. However, set the TPnCCR0 and TPnCCR1 registers to the same
value (see 6.7.1 (2) (d) Operation of TPnCCR1 register).
