Timebase Module (TBM)
TBIE — Timebase Interrupt Enabled
TBON — Timebase Enabled
228
This read/write bit enables the timebase interrupt when the TBIF bit becomes set. Reset clears the
TBIE bit.
This read/write bit enables the timebase. Timebase may be turned off to reduce power consumption
when its function is not necessary. The counter can be initialized by clearing and then setting this bit.
Reset clears the TBON bit.
1 = Timebase interrupt enabled
0 = Timebase interrupt disabled
1 = Timebase enabled
0 = Timebase disabled and the counter initialized to 0s
