* The EEPROM consists of one 2816 type EEPROM providing 2K bytes
|
|
* of electically erasable storage. To modify the EEPROM, each
|
|
* byte must be written separately. After writing each byte
|
|
* a 10 millisecond pause must be observed before the EEPROM can
|
|
* read or written again. The majority of the EEPROM is diagnostic
|
|
* and is defined in ../mon/eeprom.h. The software specific
|
|
* information (struct ee_soft) is defined here. This structure
|
|
* is 0x100 bytes big.
