TB-timer DATa bits
[The first Match period]
TB-Timer Match signal period = (1 / Fselected-clock) X (TBDAT + 1)
- Deviation period
0 <= Deviation period < (1 / Fselected-clock)
If any clock, which are divided from XSout(32.768KHz), is selected, the Deviation period can
be minimized because the Slow Clock prescaler can be cleared by software.
[The second or later Match period]
TB-Timer Match signal period = (1 / Fselected-clock) X TBDAT
(No Deviation period)
