write cycle timing

Following a start condition, the master must output the address of the slave it is accessing. The most-significant

four bits of the slave address are those of the device type identifier (see Figure 16). This is fixed as 1010 for

all devices. The EEPROM device address must be 000.

The ECLK is an output from the TNETX3150/TNETX3150A. EDIO is an input if the TNETX3150/TNETX3150A

is reading the EEPROM or an output if it is written to the EEPROM (see Figures 17 through 19).
