LVIPWRD — V
LVIREGD — V
SSREC — Short Stop Recovery Bit
STOP — STOP Instruction Enable Bit
COPD — COP Disable Bit
Freescale Semiconductor
LVIPWRD disables the V
LVIREGD disables the V
SSREC enables the CPU to exit stop mode with a delay of 32 ICLK cycles instead of a 4096 ICLK
cycle delay.
STOP enables the STOP instruction.
COPD disables the COP module. (See

If LVIPWRD=1 and LVIREGD=1, set LVIRSTD=1 before entering stop
mode.
Exiting stop mode by pulling reset will result in the long stop recovery.
If using an external crystal oscillator, do not set the SSREC bit.
When the LVI is disabled in stop mode (LVISTOP=0), the system
stabilization time for long stop recovery (4096 ICLK cycles) gives a delay
longer than the LVI’s turn-on time. 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 ICLK delay is less than the LVI’s
turn-on time and there exists a period in start-up where the LVI is not
protecting the MCU.
