Timebase Module (TBM)
9.4 Timebase Register Description
The timebase has one register, the TBCR, which is used to enable the timebase interrupts and set the
rate.
TBIF — Timebase Interrupt Flag
124
This read-only flag bit is set when the timebase counter has rolled over.
1 = Timebase interrupt pending
0 = Timebase interrupt not pending
