This subsection describes the supervisor and user modes, the five
low-power options, and test mode.
The SO bit in the Chip-Select Control Register determines whether the
processor is operating in user mode or supervisor mode. Accessing
supervisor address locations while not in supervisor mode causes the
timer to assert a transfer error. See
Register 0
Clearing the TIMEN bit in the Timer System Control Register 1
(TIMSCR1) or the PAE bit in the Pulse Accumulator Control Register
(TIMPACTL) reduces power consumption in run mode. Timer registers
are still accessible, but all timer functions are disabled. See
Timer System Control Register (TIMSCR1)
Accumulator Control Register
If the central processor unit (CPU) enters stop mode, timer operation
stops. Upon exiting stop mode, the timer resumes operation unless stop
mode was exited by reset.
The timer is unaffected by these low-power modes.
