• Counts down
• When the timer underflows, it reloads the reload register contents before
1/(n+1)
Count start flag is set (= 1)
Count start flag is reset (= 0)
Programmable I/O port
Count value is read out by reading timer Bi register
• When not counting
• When counting
Bit symbol
continuing counting
Value written to timer Bi register is written to both reload register and counter
Value written to timer Bi register is written to only reload register
(Transferred to counter at next reload time)
