(1) 16-bit counter
(2) CCR0 buffer register
Note V850E/IA4 only
Remarks 1. f
TOP3OFF
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.
The TPnCE bit is cleared to 0 after reset.
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 TPnCCR0 register is cleared to 0000H after reset, and the CCR0 buffer register is cleared to 0000H.
