/*
The next 3 bits are the A2, A1 and A0 device address bits for the 2K EEPROM.
These 3 bits must compare to their corresponding hardwired input pins.

The 4K EEPROM only uses the A2 and A1 device address bits with the third bit
being a memory page address bit. The two device address bits must compare to
their corresponding hardwired input pins. The A0 pin is no connect.

The 8K EEPROM only uses the A2 device address bit with the next 2 bits being
for memory page addressing. The A2 bit must compare to its corresponding
hard-wired input pin. The A1 and A0 pins are no connect.

The 16K does not use any device address bits but instead the 3 bits are used
for memory page addressing.

Upon a compare of the device address, the EEPROM will output a "0".
If a compare is not made, the chip will return to a standby state.
