Functional Description

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 VDD 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
