CHAPTER 16 PWC Timer
16.5
PWC Timer Interrupts
The PWC timer is enabled to generate an interrupt request in an overflow of the counter
or measurement terminated in pulse-width measurement mode. It is also coordinated
with the extended intelligent I/O service (EI
2
OS).
■
PWC Timer Interrupts
Table 16.5-1 lists the interrupt control bits and interrupt causes of the PWC timer.
In the PWC timer, the OVIR bit of the PWC control status register (PWCSL) is set to "1" by an overflow
(from FFFF
H
to 0000
H
) of the up counter. If an interrupt request is enabled (PWCSL:OVIE = 1) in this
operation, the interrupt request is output to the interrupt controller.
The EDIR bit of the PWC control status register (PWCSL) is set to "1" by measurement terminated in
pulse-width measurement mode. If an interrupt request is enabled (PWCSL:EDIE = 1) in this operation,
the interrupt request is output to the interrupt controller.
