Power Down Control Register （PWRCON）
NuMicro M051
All bits except bit6 (PD_WU_STS) are protected. Programming these protected bits needs to
write “59h”, “16h”, “88h” to address 0x5000_0100 to disable register protection. Reference the
register REGWRPROT at address GCR_BA + 0x100.

This bit control the power down entry condition
1 = Chip enter power down mode when the both PWR_DOWN_EN bit is set to 1 and CPU
run WFI instruction.
0 = Chip entry power down mode when the PWR_DOWN_EN bit is set to 1
System power down enable bit
When CPU sets this bit “1” the chip power down mode is enabled, and chip power-down
behavior will depends on the PD_WAIT_CPU bit
(a) If the PD_WAIT_CPU is “0”, then the chip enters power down mode immediately after
