The controller returns with the RPL flag set. A separate complete
message is sent by the controller with CPL flag set as soon as the read
operation has been completed.
On error the RPL, CPL and ERR flags are set and an error code is
passed in bits 15:00 of the reply word.
Notes:
The host may use any port ID that is valid for the corresponding board
when calling the flash ROM read command. It is not necessary to open
the port used before.
See section “
EKF_DOWNLOAD_PARAMS
” for a description of the
download parameter structure.
