fi : Frequency of count source
(f1, f8, f32, fC32)
Trigger is not generated by this signal
Count source
Condition : Reload register = 000316, when external trigger
(falling edge of TA0IN pin's input signal) is selected.

Cleared to “0” by software, or when interrupt request is accepted.
Note: n = 000016 to FFFE16.

fi : Frequency of count source
(f1, f8, f32, fC32)
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 FE16; n = 0016 to FE16.
Condition : Reload register's high-order 8 bits = 0216
Reload register's low-order bits 8 = 0216
When external trigger (falling edge of TA0IN pin's input signal) is selected.
