15.5 Interrupts
The timebase module can periodically interrupt the CPU with a rate
defined by the selected TBMCLK and the select bits TBR2âTBR0. 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 logic 1 to the TACK bit.
