OPERATION DURING STOP MODE
The timer system is cleared when going into STOP mode. When STOP is exited
by an external interrupt or an LVR reset or an external RESET, the internal oscilla-
tor will resume, followed by a 224 (or 4064) internal processor oscillator stabilizing
delay. The timer system counter is then cleared and operation resumes. If chosen
by a mask option, the STOP instruction will initiate HALT mode and the effects on
the timer are as described in Section 8.5.
OPERATION DURING WAIT/HALT MODE
The CPU clock halts during the WAIT/HALT mode, but the timer remains active. If
interrupts are enabled, a timer interrupt or custom periodic interrupt will cause the
processor to exit the WAIT/HALT mode.
