switched between the high-frequency and low-frequency. The timer counter 3 and 4 are cascadable to form a
16-bit TimerCouter. The warm-up counter mode has two types of mode; switching from the high-frequency to
low-frequency, and vice-versa.
Table 9-8 Setting Time of Low-Frequency Warm-Up Counter Mode (fs = 32.768 kHz)
In this mode, the warm-up period time is obtained to assure oscillation stability when the system clocking is
Note 1: In the warm-up counter mode, fix TCiCR<TFFi> to 0. If not fixed, the

is obtained. Before starting the timer, set SYSCR2<XTEN> to 1 to oscillate the low-frequency clock.
When a match between the up-counter and the timer register (TTREG4, 3) value is detected after the timer
is started by setting TC4CR<TC4S> to 1, the counter is cleared by generating the INTTC4 interrupt
request. After stopping the timer in the INTTC4 interrupt service routine, set SYSCR2<SYSCK> to 1 to
switch the system clock from the high-frequency to low-frequency, and then clear of SYSCR2<XTEN> to
0 to stop the high-frequency clock.
