(1) 16-bit counter
This 16-bit counter can count internal clocks or external events.
The count value of this counter can be read by using the TPnCNT register.
When the TPnCTL0.TPnCE bit = 0, the value of the 16-bit counter is FFFFH. If the TPnCNT register is read at this
time, 0000H is read.
Reset sets the TPnCE bit to 0. Therefore, the 16-bit counter is set to FFFFH.
(2) CCR0 buffer register
This is a 16-bit compare register that compares the count value of the 16-bit counter.
When the TPnCCR0 register is used as a compare register, the value written to 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, a compare match interrupt request signal (INTTPnCC0) is generated.
The CCR0 buffer register cannot be read or written directly.
The CCR0 buffer register is cleared to 0000H after reset, as the TPnCCR0 register is cleared to 0000H.
(3) CCR1 buffer register
This is a 16-bit compare register that compares the count value of the 16-bit counter.
When the TPnCCR1 register is used as a compare register, the value written to the TPnCCR1 register is
transferred to the CCR1 buffer register. When the count value of the 16-bit counter matches the value of the CCR1
buffer register, a compare match interrupt request signal (INTTPnCC1) is generated.
The CCR1 buffer register cannot be read or written directly.
The CCR1 buffer register is cleared to 0000H after reset, as the TPnCCR1 register is cleared to 0000H.
(4) Edge detector
This circuit detects the valid edges input to the TIPn0 and TIPn1 pins. No edge, rising edge, falling edge, or both
the rising and falling edges can be selected as the valid edge by using the TPnIOC1 and TPnIOC2 registers.
(5) Output controller
This circuit controls the output of the TOPn0 and TOPn1 pins. The output controller is controlled by the TPnIOC0
register.
(6) Selector
This selector selects the count clock for the 16-bit counter. Eight types of internal clocks or an external event can
be selected as the count clock.
