9. 8-Bit TimerCounter (TC3, TC4)
9.1 Configuration
TMP86CH47IUG
9.3.9.2
High-Frequency Warm-Up Counter Mode
(SLOW1
→
SLOW2
→
NORMAL2
→
NORMAL1)
In this mode, the warm-up period time from a stop of the high-frequency clock fc to the oscillation sta-
bility is obtained. Before starting the timer, set SYSCR2<XEN> to 1 to oscillate the high-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, clear SYSCR2<SYSCK> to 0 to
switch the system clock from the low-frequency to high-frequency, and then SYSCR2<XTEN> to 0 to
stop the low-frequency clock.
