Hi bpowers.
The MISO of WIZ550io is connected with internal MCU.
When WIZ550io’s reset is set low, MCU is reset.
Therefore, while Reset is low, the state of MISO is expected to be low.
But you do not have to worry about this.
When you are communicating with the EEPROM, you do not need to reset WIZ550io.
WIZ550io’s CS pin should be set High to communicate with EEPROM.
