Operation
(1) Prescaler
(2) Up counter (UC10)
fc
(φT0TMR) is selected by the register SYSCR0<PRCK> of clock gear. This prescaler can
be started or stopped using TB0RUN<TB0PRUN>. Counting starts when <TB0RUN>
is set to “1”; the prescaler is cleared to “0” and stops operation when <TB0RUN> is
cleared to “0”.
by TB0MOD<TB0CLK1:0>.
input via the TB0IN0 pin can be selected as the input clock. Counting or stopping and
clearing of the counter is controlled by TB0RUN<TB0RUN>.
value matches the value in the timer register TB0RG1H/L. If clearing is disabled, the
counter operates as a free running counter.
The 5-bit prescaler generates the source clock for TMRB0. The prescaler clock
The resolution of prescaler is showed in the Table 3.13.2.
UC10 is a 16-bit binary counter which counts up pulses input from the clock specified
Any one of the prescaler internal clocks φT1, φTB0 and φT16 or an external clock
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>.
