15. Timers (Timer A)
Count starts
1 / fj × (2¹⁶ - 1)
Count stops
End of 1 cycle
Count source
Input to the TAiIN pin ^"H"
"L"
TAiS bit in the TABSR 1
register
0
PWM pulse output ^"H"
from the TAiOUT pin _"L"
IR bit in the
1
TAiIC register ⁰
No trigger is generated
by this signal
Set to 1 by program
Set to 0 by program
1 / fj × m
Set to 0 by an interrupt request acknowledgement or by program
i = 0 to 4
fj: Count source frequency (f1, f8, f2n⁽¹⁾, fC32)
m: Setting value of the TAi register (0000h to FFFEh)
When the TAiS bit is set to 0 (count stops) while the
TAiOUT output is "H", the TAiOUT output becomes
"L" and the IR bit is set to 1 (interrupt requested).
(Conditions) TAi register is set to 0005h.
TAiMR register: MR1 bit is set to 1 (rising edge of signal applied to the TAiIN pin)
NOTE:
1. Bits CNT3 to CNT0 in the TCSPR register select no division (n = 0) or divide-by-2n (n = 1 to 15).
