Description

Power control register

Fields

PM

Power mode

0 (DEFAULT): Default. The part is in active or sleep mode.

1 (DEEPSLEEP): ARM WFI will enter Deep-sleep mode.

2 (POWERDOWN): ARM WFI will enter Power-down mode.

3 (DEEPPOWERDOWN): ARM WFI will enter Deep-power down mode (ARM Cortex-M0 core powered-down).

NODPD

A 1 in this bit prevents entry to Deep power-down mode when 0x3 is written to the PM field above, the SLEEPDEEP bit is set, and a WFI is executed. Execution continues after the WFI if this bit is 1. This bit is cleared only by power-on reset, so writing a one to this bit locks the part in a mode in which Deep power-down mode is blocked.

RESERVED

Reserved. Do not write ones to this bit.

SLEEPFLAG

Sleep mode flag

0 (NOPOWERDOWN): Read: No power-down mode entered. LPC11U1x is in Active mode. Write: No effect.

1 (POWERDOWN): Read: Sleep/Deep-sleep or Deep power-down mode entered. Write: Writing a 1 clears the SLEEPFLAG bit to 0.

RESERVED

Reserved. Do not write ones to this bit.

DPDFLAG

Deep power-down flag

0 (DPNOTENTERED): Read: Deep power-down mode not entered. Write: No effect.

1 (DPENTERED): Read: Deep power-down mode entered. Write: Clear the Deep power-down flag.

RESERVED

Reserved. Do not write ones to this bit.
