• Two-phase pulse signals input to TAi
• Up count or down count can be selected by two-phase pulse signal
• When the timer overflows or underflows, the reload register content is
• 1/ (FFFF
• 1/ (n + 1) for down count
Count start flag is set (= 1)
Count start flag is reset (= 0)
Two-phase pulse input (Set the corresponding function select registers A to I/
O port, and port direction register to "0")
Two-phase pulse input (Set the corresponding function select registers A to I/
O port, and port direction register to "0")
Count value can be read out by reading timer A2, A3, or A4 register
• When not counting
• When counting
• Normal processing operation (TimerA2 and timer A3)
• Multiply-by-4 processing operation (TimerA3 and timer A4)
reloaded and the timer starts over again (Note)
Value written to timer Ai register is written to both reload register and counter
Value written to timer Ai register is written to only reload register
(Transferred to counter at next reload time)
