OSCSTOPENB— Oscillator Stop Mode Enable Bar Bit

COPRS — COP Rate Select Bit
LVISTOP — LVI Enable in Stop Mode Bit
LVIRSTD — LVI Reset Disable Bit
LVIPWRD — LVI Power Disable Bit

OSCSTOPENB enables the oscillator to continue operating during stop
mode. Setting the OSCSTOPENB bit allows the oscillator to operate
continuously even during stop mode. This is useful for driving the
timebase module to allow it to generate periodic wakeup while in stop
mode. (See
SCIBDSRC controls the clock source used for the SCI. The setting of
this bit affects the frequency at which the SCI operates.
COPRS selects the COP timeout period. Reset clears COPRS. See
Computer Operating Properly
When the LVIPWRD bit is clear, setting the LVISTOP bit enables the
LVI to operate during stop mode. Reset clears LVISTOP. See
Mode.
LVIRSTD disables the reset signal from the LVI module. See
Voltage Inhibit
LVIPWRD disables the LVI module. See
