NAME
       eep24c - read and write 24Cxxx eeprom devices

SYNOPSIS
       eep24c -d device [ -r[n] filename | -w[n] filename | -k[n] filename | -f[n] 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 supported 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 values, then write whole memory)

       -f XX  Fills the whole eeprom with XX (XX is an hexadecimal value)

       n      Can be used to multiply clock time. If you have a long cable, you may use this option. Example: -r5 will read eeprom 5 times  slower
	      (pulse width will be standard value multiplied by 5). Valid range for n is from 1 to 50.	Default value is 1.

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

       eep24c -d 24c04 -r3 file.hex
	      read eeprom, write to file.hex, 3 times slower.

       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 markers.  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).
