9. TIMERS
1 / fi X (2¹⁶ – 1)
Count source
Input signal to
“H”
TAiIN pin
“L”
PWM pulse output ^{“H”}
from TAiOUT pin
“L”
IR bit of TAiIC
“1”
register
“0”
Trigger is not generated by this signal
1 / fj X n
fj : Frequency of count source
(f1, f2, f8, f32, fC32)
i = 0 to 4
Set to “0” upon accepting an interrupt request or by writing in program
Note 1: n = 000016 to FFFE16.
Note 2: This timing diagram is for the case where the TAi register is ‘000316,’ the TAiTGH and TAiTGL bits of ONSF
or TRGSR register = ‘002’ (TAiIN pin input), the MR1 bit of TAiMR register = 1 (rising edge), and the MR2
bit of TAiMR register = 1 (trigger selected by TAiTGH and TAiTGL bits).

i = 0 to 4
Set to “0” upon accepting an interrupt request or by writing in program
Note 1: The 8-bit prescaler counts the count source.
Note 2: The 8-bit pulse width modulator counts the 8-bit prescaler's underflow signal.
Note 3: m = 0016 to FF16; n = 0016 to FE16.
Note 4: This timing diagram is for the case where the TAi register is ‘020216,’ the TAiTGH and TAiTGL bits of ONSF or
TRGSR register = ‘002’ (TAiIN pin input), the MR1 bit of TAiMR register = 0 (falling edge), and the MR2 bit of
TAiMR register = 1 (trigger selected by TAiTGH and TAiTGL bits).
