This section describes the timebase module (TBM). The TBM will
generate periodic interrupts at user selectable rates using a counter
clocked by the selected OSCCLK clock from the oscillator module. This
TBM version uses 18 divider stages, eight of which are user selectable.
Features of the TBM module include:
•
•
Software programmable 8s, 4s, 2s, 1s, 2ms, 1ms, 0.5ms, and
0.25ms periodic interrupt using 32.768-kHz OSCCLK clock
User selectable oscillator clock source enable during stop mode to
allow periodic wake-up from stop
