Description

Current image
Flash offset of the currently running application image.
2-3
Failing image
Flash offset of the highest priority failing application
image. If multiple images are available in flash memory,
stores the value of the first image that failed. A value of
all 0s indicates no failing images. If there are no failing
images, the remainder of the remaining words of the
status information do not store valid information.
Note: A rising edge on
nCONFIG

Client receives a new
RSU_IMAGE_UPDATE
command and successfully configures from the
update image.
