LPMD
Low-power mode select. Used to select the low-power mode the chip
enters once the ColdFire CPU executes the STOP instruction. These bits
must be written prior to instruction execution for them to take effect. The
LPMD[1:0] bits are readable and writable in all modes.
the four different power modes that can be configured with the LPMD bit
field.
Reserved, should be cleared.
PLL/CLKOUT stop mode. Controls PLL and CLKOUT operation in stop
mode as shown in
Reserved, should be cleared.
LDV standby enable. Controls whether the PMM enters VREG Standby
Mode (LVD disabled) or VREG Pseudo-Standby (LVD enabled) mode when
the PMM receives a power down request. This bit has no effect if the
RCR[LVDE] bit is a logic 0.
1 VREG Pseudo-Standby mode (LVD enabled on power down request).
0 VREG Standby mode (LVD disabled on power down request).
Reserved, should be cleared.
