Clocks and Power Control
The default value of the LME bit is determined by MODCK[1:3] during assertion of the PORESET line.
The configuration modes are shown in
8.7
The LPM and other bits in the PLPRCR are encoded to provide one normal operating mode and four
low-power modes. In normal and doze modes the system can be in high state with frequency defined by
the DFNH bits, or in the low state with frequency defined by the DFNL bits. The normal-high operating
mode is the state out of reset. This is also the state of the bits after the low-power mode exit signal arrives.
There are four low-power modes:
8.7.1
Low-power modes are enabled by setting the MSR[POW] and clearing the SCCR[LPML]. Once enabled,
a low-power mode is entered by setting the LPM bits to the appropriate value. This can be done only in
one of the normal modes. The user cannot change the PLPRCR[LPM or CSRC] when the MCU is in doze
mode.

Entering a Low-Power Mode
At least one of the two bits, LOCSS or BUCS, must be asserted (one) in this state.

The switching from state three to state four is accomplished by clearing the
STBUC and LOCSS bits. If the switching is done when the PLL is not
locked, the system clock will not oscillate until lock condition is met.
Higher than desired currents during low-power mode can be avoided by
executing a mullw instruction before entering the low-power mode, i.e.,
anytime after reset and prior to entering the low-power mode.
