Count source
Input signal to
TAiIN pin
Underflow signal of
8-bit prescaler
IR bit in TAiIC
register
i = 0 to 4
fj: Frequency of count source (f1, f2, f8, f32, fC32)
NOTES:
PWM pulse output
from TAiOUT pin
1. The 8-bit prescaler counts the count source.
2. The 8-bit pulse width modulator counts the output from the 8-bit prescaler underflow signal.
3. m = 00h to FFh; n = 00h to FEh.
4. This timing diagram is the following case.

TAi register = 0202h
Bits TAiTGH and TAiTGL in the ONSF or TRGSR register = 00b (TAiIN pin input)
The MR1 bit in the TAiMR register = 0 (falling edge)
The MR2 bit in the TAiMR register = 1 (trigger selected by bits TAiTGH and TAiTGL)
1. n = 0000h to FFFEh.
2. This timing diagram is the following case.
TAi register = 0003h
Bits TAiTGH and TAiTGL in the ONSF or TRGSR register = 00b (TAiIN pin input)
The MR1 bit in the TAiMR register = 1 (rising edge)
The MR2 bit in the TAiMR register = 1 (trigger selected by bits TAiTGH and TAiTGL)
