TCG Clear Timing: TCG can be cleared at the rising edge, falling edge, or both edges of the

external input capture signal. Figure 9.12 shows the timing for clearing at both edges.

Note: * In active mode and sleep mode, if ø

W/2 is selected as the TCG internal clock, since the

system clock and internal clock are not synchronized with each other, a synchronization

circuit is used. This may result in a count cycle error of up to 1/ø (s). In subactive mode and

subsleep mode, if ø

W/2 is selected as the TCG internal clock, regardless of the subclock

ø/SUB (ø

W/2, øW/4, øW/8) TCG and the noise canceller circuit run on an internal clock of

W/2. If any other internal clock is chosen, TCG and the noise canceller circuit will not run,

and the input capture function will not operate.
