Device Addressing
Following a start condition, the master must output a Slave
Address Byte. The first four bits of the Slave Address Byte
specify access to either the EEPROM array or to the CCR.
Slave bits ‘1010’ access the EEPROM array. Slave bits
‘1101’ access the CCR.
When shipped from the factory, EEPROM array is
UNDEFINED, and should be programmed by the customer
to a known state.
Bit 3 through Bit 1 of the slave byte specify the device select
bits. These are set to ‘111’.
The last bit of the Slave Address Byte defines the operation
to be performed. When this R/W bit is a one, then a read
