DATA
This subroutine both compares data passed in the DATA array to the FLASH data
and reads the data from FLASH into the DATA array. It also calculates the
checksum of the data.
This subroutine dumps the data from the range to PA0 in the same format as
monitor data. It also calculates the checksum of the data.
This serial dump does not circumvent security because the security vectors must
still be passed to make FLASH readable in monitor mode.
