Prepare sector(s) for write operation
Command code: 50
Param0: Start Sector Number
Param1: End Sector Number (should be greater than or equal to start sector
number).
CMD_SUCCESS |
BUSY |
INVALID_SECTOR
None
This command must be executed before executing "Copy RAM to Flash" or
"Erase Sector(s)" command. Successful execution of the "Copy RAM to Flash" or
"Erase Sector(s)" command causes relevant sectors to be protected again. The
boot sector can not be prepared by this command. To prepare a single sector use
the same "Start" and "End" sector numbers.
Copy RAM to Flash
Command code: 51
Param0(DST): Destination Flash address where data bytes are to be written. This
address should be a 256 byte boundary.
Param1(SRC): Source RAM address from which data bytes are to be read. This
address should be a word boundary.
Param2: Number of bytes to be written. Should be 256 | 512 | 1024 | 4096.
Param3: System Clock Frequency (CCLK) in kHz.
CMD_SUCCESS |
SRC_ADDR_ERROR (Address not a word boundary) |
DST_ADDR_ERROR (Address not on correct boundary) |
SRC_ADDR_NOT_MAPPED |
DST_ADDR_NOT_MAPPED |
COUNT_ERROR (Byte count is not 256 | 512 | 1024 | 4096) |
SECTOR_NOT_PREPARED_FOR_WRITE_OPERATION |
BUSY |
None
This command is used to program the Flash memory. The affected sectors should
be prepared first by calling "Prepare Sector for Write Operation" command. The
affected sectors are automatically protected again once the copy command is
successfully executed. The boot sector can not be written by this command.
