Member Function Documentation

int blank_check ( int  start,
int  end 
)

Blank check sector(s)

Parameters:
starta Start Sector Number
endan End Sector Number (should be greater than or equal to start sector number).
Returns:
error code: CMD_SUCCESS | BUSY | SECTOR_NOT_BLANK | INVALID_SECTOR

Definition at line 96 of file IAP.cpp.

int compare ( char *  source_addr,
char *  target_addr,
int  size 
)

Compare <address1> <address2> <no of="" bytes>="">

Parameters:
source_addrStarting flash or RAM address of data bytes to be compared. This address should be a word boundary.
target_addrStarting flash or RAM address of data bytes to be compared. This address should be a word boundary.
sizeNumber of bytes to be compared; should be a multiple of 4.
Returns:
error code: CMD_SUCCESS | COMPARE_ERROR | COUNT_ERROR (Byte count is not a multiple of 4) | ADDR_ERROR | ADDR_NOT_MAPPED

Definition at line 173 of file IAP.cpp.

int erase ( int  start,
int  end 
)

Erase Sector(s)

Parameters:
starta Start Sector Number
endan End Sector Number (should be greater than or equal to start sector number).
Returns:
error code: CMD_SUCCESS | BUSY | SECTOR_NOT_PREPARED_FOR_WRITE_OPERATION | INVALID_SECTOR

Definition at line 114 of file IAP.cpp.

int prepare ( int  start,
int  end 
)

Prepare sector(s) for write operation.

Parameters:
starta Start Sector Number
endan End Sector Number (should be greater than or equal to start sector number).
Returns:
error code: CMD_SUCCESS | BUSY | INVALID_SECTOR

Definition at line 133 of file IAP.cpp.

int read_eeprom ( char *  source_addr,
char *  target_addr,
