Figure 8-4-1 Count Timing of Timer Operation (Time Base Timer)

When the selected interrupt cycle has passed, the interrupt request flag of the time base interrupt control register (TBICR) is set to "1".

An interrupt may be generated at switching of the clock source. Enable interrupt after switch- ing the clock source.

Time base timer cannot stop the operation.

The initialization can be done by writing an arbitrary value to the time base timer clear control register (TBCLR).
