Timebase Module (TBM)
17.4 Timebase Register Description
The timebase has one register, the timebase control register (TBCR), which is used to enable the
timebase interrupts and set the rate.
TBIF — Timebase Interrupt Flag
218
This read-only flag bit is set when the timebase counter has rolled over.
TBMCLK
1 = Timebase interrupt pending
0 = Timebase interrupt not pending
