Power Management I2C

The power management I²C signals are available in different locations on the conga-SEVAL. The conga-SEVAL includes socket P21 for an
I²C EEPROM (U42). The EEPROM is connected to the power management bus, in the module's power domain. This connection enables the
module to obtain carrier board parameters from the EEPROM, before asserting the CARRIER_PWR_ON signal.
The conga-SEVAL features an Atmel 24C32 EEPROM on the 8-pin DIL socket (P21). The address inputs (A0 - A2) of the EEPROM are set to
binary 111.
