n Pulse Width Count Timer Registers
PCR1 (PWC pulse width control register 1)
PCR2 (PWC pulse width control register 2)
RLBR (PWC reload buffer register)
R/W: Readable and writable
R : Read-only
— : Unused
X : Indeterminate
n Pulse Width Count Timer Interrupt Source
IRQ5: For both the interval timer and pulse width measurement functions, the PWC generates
an interrupt request if interrupt request output is enabled (PCR1: IE = "1") when the
counter value underflows (01
Also, for the pulse width measurement function, the PWC also generates an interrupt
request for the pulse width measurement function if interrupt request output is enabled
(PCR1: IE = "1") when pulse width measurement completes or a pulse width
measurement value remains in the RLBR register.
