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.
For further information regarding timers on M68HC08 family devices,
please consult the HC08 Timer Reference Manual, TIM08RM/AD.
Features of the TBM module include:
