• Down-count
• When the timer underflows, it reloads the reload register contents and
1/(n+1) n: set value of TAi register (i= 0 to 4) 0000h to FFFFh
Set TAiS bit in TABSR register to “1” (= start counting)
Set TAiS bit to “0” (= stop counting)
Timer underflow
I/O port or gate input
I/O port or pulse output
Count value can be read by reading TAi register
• When not counting and until the 1st count source is input after counting start
• When counting (after 1st count source input)
• Gate function
• Pulse output function
continues counting
Value written to TAi register is written to both reload register and counter
Value written to TAi register is written to only reload register
(Transferred to counter when reloaded next)
Counting can be started and stopped by an input signal to TAiIN pin
Whenever the timer underflows, the output polarity of TAiOUT pin is inverted.
When TAiS bit is set to “0” (stop counting), the pin outputs a low.
