or (0,1). Note: in (PS1,PS0) = (0,0) mode, the chip will
start automatically, after trying to read the external
EEPROM. If EEPROM does not exist, the chip will use
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 = 0x95,
(2) Register 1 [7:4] = 0x0. If this check is OK, the
contents in the EEPROM will override chip register
default values.=0, chip will not start when external pins
(PS1, PS0) = (1,0) or (0,1).
Note: (PS1, PS0) = (1,1) for factory test only.
