Resets and Interrupts
13.3.2.11 Timebase Module (TBM)
The timebase module can interrupt the CPU on a regular basis with a rate defined by TBR2–TBR0. When
the timebase counter chain rolls over, the TBIF flag is set. If the TBIE bit is set, enabling the timebase
interrupt, the counter chain overflow will generate a CPU interrupt request.
Interrupts must be acknowledged by writing a 1 to the TACK bit.
13.3.3 Interrupt Status Registers
The flags in the interrupt status registers identify maskable interrupt sources.
interrupt sources and the interrupt status register flags that they set. The interrupt status registers can be
useful for debugging.
