Note: * When φw/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). When
φw/4 is selected as the TCG internal clock in watch mode, TCG and the noise canceler
operate on the φw/4 internal clock without regard to the φ_SUB subclock (φw/8, φw/4, φw/2).
Note that when another internal clock is selected, TCG and the noise canceler do not
operate, and input of the input capture input signal does not result in input capture.
To operate the timer G in subactive mode or subsleep mode, select φw/4 as the TCG
internal clock and φw/2 as the subclock φ_SUB. Note that when other internal clock is
selected, or when φw/8 or φw/4 is selected as the subclock φ_SUB, TCG and the noise
canceler do not operate.
