Scanner I/F EEPROM
R/W Test
Description
This test checks the read and write functions of EEPROM for the
Option 301 Scanner Interface. When this test is started, a bit
pattern is written to the lower address of the EEPROM, then the
write pattern is checked by reading back the bit pattern. This write
pattern check is rep eated from low to high EEPROM addresses.
