trying to read the external EEPROM. If EEPROM does not
exists, the chip will use pin strapping and default values for all
internal registers. If EEPROM is present, the contents in the
EEPROM will be checked. The switch will check: (1) Register 0
= 0x93, (2) Register 1 bits [7:4] = 0x0. If this check is OK, the
contents in the EEPROM will override chip register default
values.
