The I2C slave address of the DS3901 depends on the
state of the ADD_SEL pin. If this pin is low, then the
slave address is fixed at A2h. If the ADD_SEL pin is
high, then the slave address is determined by the value
stored in EEPROM at address 9Fh. Factory default
value for the slave address is A0h. The seven most sig-
nificant bits are used (the LSB is not used because it is
in the bit position of the R/W bit) to allow the slave
address to be programmed to one of 128 possible
addresses.
