Param1(SRC): Source RAM address from which data bytes are to be read. This address should be
on word boundary.
Param2: Number of bytes to be written. Should be 512 | 1024 | 4096 | 8192.
Param3: System Clock Frequency (CCLK) in KHz.
CMD_SUCCESS |
SRC_ADDR_ERROR (Address not on word boundary) |
DST_ADDR_ERROR (Address not on correct boundary) |
SRC_ADDR_NOT_MAPPED |
DST_ADDR_NOT_MAPPED |
COUNT_ERROR (Byte count is not 512 | 1024 | 4096 | 8192) |
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.
Erase Sector(s)
Command code: 52
Param0: Start Sector Number
Param1: End Sector Number: Should be greater than or equal to start sector number.
Param2: System Clock Frequency (CCLK) in KHz.
CMD_SUCCESS |
BUSY |
SECTOR_NOT_PREPARED_FOR_WRITE_OPERATION |
INVALID_SECTOR

This command is used to erase a sector or multiple sectors of on-chip Flash memory. The boot
sector can not be erased by this command. To erase a single sector use the same "Start" and "End"
