PVs of high-speed
counters and pulse
outputs when an inter-
rupt occurs
Update method for Updating interrupt counter SV in Auxil-
interrupt counter SV iary Area and then executing
(Counter Mode) MSKS(690) again to enable interrupts
Update method for INI(880) instruction
interrupt counter PV
(Counter Mode)
Update timing for • Every cycle
interrupt counter PV
• When count completion interrupt
(Counter Mode)
occurs
• When PRV(881) instruction is exe-
cuted
Operation of interrupt Counter operation continued, but inter-
counters when inter- rupt will not occur at count completion
rupts are disabled with
DI(693)
