Table 1 summarizes the operating modes of PXD10 devices.

Table 1. Operating mode summary1

NOTES:

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

Wake-up time2

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 durations

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
