Table 590. IAP Copy RAM to Flash command
Command Copy RAM to Flash
Input Command code: 51
(decimal)
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: CPU Clock Frequency (CCLK) in kHz.
Return Code 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 |
Result None
Description 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.
Table 591. IAP Erase Sector(s) command
Command Erase Sector(s)
Input Command code: 52
(decimal)
Param0: Start Sector Number
Param1: End Sector Number (should be greater than or equal to start sector
number).
Param2: CPU Clock Frequency (CCLK) in kHz.
Return Code CMD_SUCCESS |
BUSY |
SECTOR_NOT_PREPARED_FOR_WRITE_OPERATION |
INVALID_SECTOR
Result None
Description This command is used to erase a sector or multiple sectors of on-chip flash
memory. To erase a single sector use the same "Start" and "End" sector numbers.
