@WDT(94) TWDT(94) T
When the execution condition is OFF, WDT(94) is not executed. When the
execution condition is ON, WDT(94) extends the setting of the watchdog tim-
er (normally set by the system to 130 ms) by 100 ms times T.
Timer extension = 100 ms x T.
Precautions If the cycle time is longer than the time set for the watchdog timer, 9F will be
output to the FAL area and the CPU will stop.
If the cycle time exceeds 6,500 ms, a FALS 9F will be generated and the sys-
tem will stop.
Timers might not function properly when the cycle time exceeds 100 ms.
When using WDT(94), the same timer should be repeated in the program at
intervals that are less than 100 ms apart. TIMH(15) should be used only in a
scheduled interrupt routine executed at intervals of 10 ms or less.
Flags There are no flags affected by this instruction.
