The 5-bit prescaler generates the source clock for timer 0. The prescaler clock (φT0) is
This prescaler can be started or stopped using TB0RUN<TB0PRUN>. Counting
UC10 is a 16-bit binary counter which counts up pulses input from the clock specified
Any one of the prescaler internal clocks φT1, φT4 and φT16 can be selected as the
When clearing is enabled, the up counter UC10 will be cleared to 0 each time its
Clearing can be enabled or disabled using TB0MOD<TB0CLE>.
A timer overflow interrupt (INTTBOF0) is generated when UC10 overflow occurs.
