Start Switch
1, start the chip when external pins (PS1, PS0) = (1,0) 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.
