Setting the EEPROM Lower Address Bits (J4, J5, J6)
The 32KB I²C EEPROM populating U17 on the phyCORE-module has the capability of configuring the
lower address bits A0, A1, and A2. The four upper address bits of the device are fixed at ‘1010’ (
see
ST 24W32C data sheet).
The remaining three lower address bits of the seven bit I²C device address
are configurable using jumpers J4, J5 and J6. J4 sets address bit A0, J5 address bit A1, and J6
address bit A2.
Table 9 below shows the resulting seven bit I²C device address for the eight possible jumper
configurations.
