External signals fed to CNTR
• Down count
• When the timer underflows, the contents in the reload register is reloaded and the count
1/(n+1)(m+1)
Write “1” (count start) to TXS bit in TXMR register
Write “0” (count stop) to TXS bit in TXMR register
• When Timer X underflows [Timer X interrupt]
Count source input (INT1 interrupt input)
Programmable I/O port
Count value can be read by reading TX register
Same applies to PREX register.
Value written to TX register is written to both reload register and counter.
Same applies to PREX register.
