1/ (FFFFh - n + 1) for up-count
1/ (n + 1) for down-count
Set the TAiS bit in the TABSR register to 1 (count starts)
Set the TAiS bit to 0 (count stops)
Two-phase pulse input
Two-phase pulse input
Count value can be read by reading the TAi register
• Two-phase pulse signals input to TAiIN or TAiOUT pins
• Up-count or down-count can be selected by two-phase pulse signal
• When the timer overflows or underflows, it reloads the reload register
• When not counting and until the 1st count source is input after counting start
• When counting (after 1st count source input)
• Normal processing operation (timers A2 and A3)
• Multiply-by-4 processing operation (timers A3 and A4)
• Counter initialization by Z-phase input (timer A3)
contents and continues counting. When operating in free-running mode,
the timer continues counting without reloading.
Value written to TAi register is written to both reload register and counter
Value written to TAi register is written to reload register
(Transferred to counter when reloaded next)
The timer counts up rising edges or counts down falling edges on TAjIN
pin when input signals on TAjOUT pin is “H”.
If the phase relationship is such that TAkIN pin goes “H” when the input
signal on TAkOUT pin is “H”, the timer counts up rising and falling edges
on pins TAkOUT and TAkIN. If the phase relationship is such that TAkIN
pin goes “L” when the input signal on TAkOUT pin is “H”, the timer counts
down rising and falling edges on pins TAkOUT and TAkIN.
The timer count value is initialized to 0 by Z-phase input.
