Condition : Reload register high-order 8 bits = 0216
Reload register low-order 8 bits = 0216
Timer overflow is selected
Count source (Note1)
1 / fi X (m + 1) X (2 ⁸ – 1)
Timer overflow
“H”
“L”
Underflow signal of ^{“H”}
8-bit prescaler (Note2) _{“L”}
PWM pulse output ^{“H”}
from TAiOUT pin
“L”
Timer Ai interrupt
“1”
request bit
“0”
1 / fi X (m + 1)
1 / fi X (m + 1) X n
fi : Frequency of count source
(f1, f8, f32, fC32)
Cleared to “0” when interrupt request is accepted, or cleared by software
Notes 1: The 8-bit prescaler counts the count source.
2: The 8-bit pulse width modulator counts the 8-bit prescaler's underflow signal.
3: m = 0016 to FE16; n = 0016 to FE16.
