LVIPWRD — LVI Power Disable Bit
LVIPWRD disables the LVI module.
1 = LVI module power disabled
0 = LVI module power enabled
LVITRIP — LVI Trip Point Selection Bit
LVITRIP selects the voltage operating mode of the LVI module. The voltage mode selected for the LVI
should match the operating V
DD
for the LVI’s voltage trip points for each of the modes.
1 = LVI operates for a 5-V protection
0 = LVI operates for a 3.3-V protection
NOTE
The LVITRIP bit is cleared by a power-on reset (POR) only. Other resets
will leave this bit unaffected.
SSREC — Short Stop Recovery Bit
SSREC enables the CPU to exit stop mode with a delay of 32 BUSCLKX4 cycles instead of a 4096
BUSCLKX4 cycle delay.
1 = Stop mode recovery after 32 BUSCLKX4 cycles
0 = Stop mode recovery after 4096 BUSCLKX4 cycles
NOTE
Exiting stop mode by an LVI reset will result in the long stop recovery.
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.
1 = COP module disabled
0 = COP module enabled
