LVIPWRD — Low Voltage Inhibit Power Disable
LVIPWRD disables the LVI module. This bit is reset to 0 by a POR only.
1 = LVI module disabled
0 = LVI module enabled
NOTE
Exiting stop mode by pulling reset will result in the long stop recovery. If
using an external crystal, do not set the SSREC bit.
SSREC — Short Stop Recovery Bit
SSREC enables the CPU to exit stop mode with a delay of 32 CGMXCLK cycles instead of a 4096
CGMXCLK cycle delay.
1 = Stop mode recovery after 32 CGMXCLK cycles
0 = Stop mode recovery after 4096 CGMXCLK cycles
STOP — STOP Instruction Enable Bit
STOP enables the STOP instruction.
1 = STOP instruction enabled
0 = STOP instruction treated as illegal opcode
COPD — COP Disable Bit
COPD disables the COP module. Reset clears COPD.
1 = COP module disabled
0 = COP module enabled

STOP_XCLKEN — Crystal Oscillator Stop Mode Enable (OSC)
Setting STOP_XCLKEN enables the crystal oscillator on OSC1 and OSC2 to continue operating
during stop mode. Reset clears this bit.
1 = Crystal oscillator enabled on OSC pins during stop mode
0 = Crystal oscillator disabled on OSC pins during stop mode
STOP_XTALEN — Crystal Oscillator Stop Mode Enable (XTAL)
Setting STOP_XTALEN enables the crystal oscillator on XTAL1 and XTAL2 to continue operating
during stop mode. Reset clears this bit.
1 = Crystal oscillator enabled on XTAL pins during stop mode
0 = Crystal oscillator disabled on XTAL pins during stop mode
