AHB, APB and all peripherals
operational at full speed
All clocks to core and peripherals
stopped
Faster wake enabled by keeping
LFOSC0 or RTC0TCLK active

Core halted
AHB, APB and all peripherals
operational at low speed
Low power sleep
LDO regulators are disabled and all
active circuitry operates directly from
VBAT
The following functions are available:
ACCTR0, RTC0, UART0 running
from RTC0TCLK, LPTIMER0, port
match, and the LCD controller
Register and RAM state retention

Full device operation
Full device operation
Higher CPU bandwidth than PM0 (RAM
can operate with zero wait states at any
frequency)
Fast wakeup from any interrupt source
Wake on any wake source or reset
source defined in the PMU
Same capabilities as PM0, operating at
lower speed
Lower clock speed enables lower LDO
output settings to save power
Same capabilities as PM1, operating at
lower speed
Lower clock speed enables lower LDO
output settings to save power
Same capabilities as PM2, operating at
lower speed
Lower clock speed enables lower LDO
output settings to save power
When running from LFOSC0, power is
similar to PM3, but the device wakes
much faster
Lowest power consumption
Wake on any wake source or reset
source defined in the PMU
