EEP24C(1)                                               EEP24C(1)

NAME
       eep24c - read and write 24Cxxx eeprom devices

SYNOPSIS
       eep24c -d device [ -r filename | -w filename | -k filename
       | -f xx ]

DESCRIPTION
       The command eep24c can be used to read  and  write  24Cxxx
       eeprom devices.

OPTIONS
       The following options are available:

       -d device
              Specify  the device type. To see a list of the sup­
              ported devices, try -d help

       -r filename
              Read from eeprom and save to a file.

       -w filename
              Read  from  a  file  and  write  to  eeprom.    The
              addresses  not  specified in the input file will be
              filled with 00.

       -k filename
              Read  from  a  file  and  write  to  eeprom.    The
              addresses  not  specified in the input file will be
              kept with its previous values. (this mode is  twice
              slower. It reads whole memory to know previous val­
              ues, then write whole memory)

       -f XX  Fills the whole eeprom with XX (xx is an  hexadeci­
              mal value)

USAGE EXAMPLES
       eep24c -d 24c04 -r file.hex
              read eeprom, write to file.hex

       eep24c -d 24c04 -w file.hex
              read file.hex and write to eeprom. All the bytes not
              found in file.hex will be written as 00.

       eep24c -d 24c04 -k file.hex
              read file.hex and write to eeprom. All the bytes not
              found in file.hex will remain unchanged.

       eep24c -d 24c04 -f 7A
              fill eeprom with 7A (hexadecimal).

INPUT AND OUTPUT FORMAT
       Input  and  output file format is Intel Hexadecimal Object
       File Format
       You can find this specification at
       ftp://download.intel.com/support/processors/
       i960/devtools/INTELHEX.PDF
       Record types 00 and 01 are implemented  in  this  version.
       In input lines, LF and CR+LF are accepted as newline mark­
       ers.  Output files are generated  with  LF  as  a  newline
       marker.

DEVICE SPECIFIC
       If you are using Microchip 24*515, you must tie its pin A2
       to VCC (needs  a  hardware modification, see device
       datasheet).
