(a) If the PDWTCPU is 0, then the chip enters Power-down mode immediately after the PDEN bit set. (default) (b) if the PDWTCPU is 1, then the chip keeps active till the CPU sleep mode is also active and then the chip enters Power-down mode. When chip wakes up from Power-down mode, this bit is auto cleared. Users need to set this bit again for next Power-down. In Power-down mode, HXT and the HIRC will be disabled in this mode, but LXT and LIRC are not controlled by Power-down mode. In Power-down mode, the PLL and system clock are disabled, and ignored the clock source selection. The clocks of peripheral are not controlled by Power-down mode, if the peripheral clock source is from LXT or LIRC. Note: This bit is write protected.
