This section describes the timebase module (TBM). The TBM will
generate periodic interrupts at user selectable rates using a counter
clocked by the external crystal clock. This TBM version uses 15 divider
stages, eight of which are user selectable.
Features of the TBM module include:
•
•
Software programmable 1-Hz, 4-Hz, 16-Hz, 256-Hz, 512-Hz,
1024-Hz, 2048-Hz, and 4096-Hz periodic interrupt using external
32.768-kHz crystal
User selectable oscillator clock source enable during stop mode to
allow periodic wakeup from stop
