When the LVIPWRD bit is clear, setting the LVISTOP bit enables the LVI to operate during stop mode.
Reset clears LVISTOP.
LVIRSTD disables the reset signal from the LVI module.
LVIPWRD disables the LVI module.
LVITRIP selects the voltage operating mode of the LVI module. The voltage mode selected for the LVI
should match the operating V
SSREC enables the CPU to exit stop mode with a delay of 32 BUSCLKX4 cycles instead of a 4096
BUSCLKX4 cycle delay.
When using the LVI during normal operation but disabling during stop mode, the LVI will have an
enable time of t
BUSCLKX4 cycles) gives a delay longer than the LVI enable time for these startup scenarios. There
is no period where the MCU is not protected from a low-power condition. However, when using the
short stop recovery configuration option, the 32 BUSCLKX4 delay must be greater than the LVI’s turn
on time to avoid a period in startup where the LVI is not protecting the MCU.
STOP enables the STOP instruction.
COPD disables the COP module.
1 = LVI enabled during stop mode
0 = LVI disabled during stop mode
1 = LVI module resets disabled
0 = LVI module resets enabled
1 = LVI module power disabled
0 = LVI module power enabled
1 = LVI operates for a 5-V protection
0 = LVI operates for a 3.3-V protection
1 = Stop mode recovery after 32 BUSCLKX4 cycles
0 = Stop mode recovery after 4096 BUSCLKX4 cycles
1 = STOP instruction enabled
0 = STOP instruction treated as illegal opcode
1 = COP module disabled
0 = COP module enabled
The LVITRIP bit is cleared by a power-on reset (POR) only. Other resets
will leave this bit unaffected.
Exiting stop mode by an LVI reset will result in the long stop recovery.
