Note: 1. When φ
W
/4 is selected as the TCG internal clock in active mode or sleep mode, since
the system clock and internal clock are mutually asynchronous, synchronization is
maintained by a synchronization circuit. This results in a maximum count cycle error of
1/φ(s).
2. When φ
W
/4 is selected as the TCG internal clock in watch mode, TCG and the noise
canceller operate on the φ
W
/4 internal clock without regard to the φ
SUB
subclock (φ
W
/8,
φ
W
/4, φ
W
/2). Note that when another internal clock is selected, TCG and the noise
canceller do not operate, and input of the input capture input signal does not result in
input capture.
3. To operate the timer G in subactive mode or subsleep mode, select φ
W
/4 as the TCG
internal clock and φ
W
/2 as the subclock φ
SUB
. Note that when other internal clock is
selected, or when φ
W
/8 or φ
W
/4 is selected as the subclock φ
SUB
, TCG and the noise
canceller do not operate.
