Address:
The core timer counter register is a read-only register, which contains
the current value of the 8-bit ripple counter at the beginning of the timer
chain. Reset clears this register.
The CPU clock halts during the WAIT mode, but the core timer remains
active. If the CTIMER interrupts are enabled, then a CTIMER interrupt
will cause the processor to exit the WAIT mode.
The timer is cleared when going into STOP mode. When STOP is exited
by an external interrupt or an external reset, the internal oscillator will
restart, followed by an internal processor stabilization delay (t
timer is then cleared and operation resumes.
