value matches the value in the timer register TB0RG1H/L. Clearing can be enabled or
disabled using TB0MOD<TB0CLE>.
The 5-bit prescaler generates the source clock for TMRB0. The prescaler clock (φT0)
This prescaler can be started or stopped using TB0RUN<TB0PRUN>. Counting
Table 3.8.2 show prescaler output clock resolution.
UC10 is a 16-bit binary counter that counts up according to input from the clock
As the input clock, one of the prescaler internal clocks φT1, φT4, and φT16 can be
When clearing is enabled, the up counter UC10 will be cleared to zero each time its
If clearing is disabled, the counter operates as a free-running counter.
A timer overflow interrupt (INTTBOF0) is generated when UC10 overflow occurs.
