LVIPWRD — LVI Power Disable Bit
LVI5OR3 — LVI 5-V or 3-V Operating Mode Bit
SSREC — Short Stop Recovery Bit
STOP — STOP Instruction Enable Bit
COPD — COP Disable Bit
Freescale Semiconductor
LVIPWRD disables the LVI module.
LVI5OR3 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.
The system stabilization time for power-on reset and long stop recovery (both 4096 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 module power disabled
0 = LVI module power enabled
1 = LVI operates in 5-V mode
0 = LVI operates in 3-V mode
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 LVI5OR3 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.
