Table Key:
On—Powered and clocked
OP—Optionally configurable to be enabled or disabled (clock gated)
CG—Clock Gated, Powered but clock stopped
Off—Powered off and clock gated
FP—VREG Full Performance mode
LP—VREG Low Power mode, reduced output capability of VREG but lower power consumption
Var—Variable duration, based on the required reconfiguration and execution clock speed
BAM—Boot Assist Module Software and Hardware used for device start-up and configuration
A high level summary of some key durations that need to be considered when recovering from low power modes. This does not account for all duration
at wake up. Other delays will be necessary to consider including, but not limited to the external supply start-up time.
IRC Wake-up time must not be added to the overall wake-up time as it starts in parallel with the VREG.
All other wake-up times must be added to determine the total start-up time
The LCD can optionally be kept running while the device is in STANDBY mode.
All of the RAM contents is retained, but not accessible in STANDBY mode.
8 KB of the RAM contents is retained, but not accessible in STANDBY mode.
