• External signals input to TBiIN pin (effective edge can be selected in program)
• Timer Bj overflow or underflow
• Down-count
• When the timer underflows, it reloads the reload register contents and
1/(n+1) n: set value of the TBi register
Set TBiS bit
Set TBiS bit to 0 (count stops)
Count source input
Count value can be read by reading the TBi register
• When not counting and until the 1st count source is input after counting start
• When counting (after 1st count source input)
b0
continues counting
Value written to the TBi register is written to both reload register and counter
Value written to the TBi register is written to only reload register
(Transferred to counter when reloaded next)
