14. 8-bit Timer Counter (TC0)
TMP89FM42
RA002
14.3 Low Power Consumption Function
Timer counters 00 and 01 have the low power consumption registers (POFFCR0) that save power when the timers
are not used.
Setting POFFCR0<TC001EN> to "0" disables the basic clock supply to timer counters 00 and 01 to save power.
Note that this renders the timers unusable. Setting POFFCR0<TC001EN> to "1" enables the basic clock supply to
timer counters 00 and 01 and allows the timers to operate.
After reset, POFFCR0<TC001EN> are initialized to "0", and this makes the timers unusable. When using the tim-
ers for the first time, be sure to set POFFCR0<TC001EN> to "1" in the initial setting of the program (before the
timer control registers are operated).
Do not change POFFCR0<TC001EN> to "0" during the timer operation. Otherwise timer counters 00 and 01 may
operate unexpectedly.
