Table 4 General Purpose I/O Pins (Part 1 of 4)
Master SMBus Address. These pins determine the SMBus address of the serial
EEPROM from which configuration information is loaded.
Master SMBus Clock. This bidirectional signal is used to synchronize transfers on the
master SMBus. It is active and generating the clock only when the EEPROM or I/O
Expanders are being accessed.
Master SMBus Data. This bidirectional signal is used for data on the master SMBus.
Slave SMBus Address. These pins determine the SMBus address to which the slave
SMBus interface responds.
Slave SMBus Clock. This bidirectional signal is used to synchronize transfers on the
slave SMBus.
Slave SMBus Data. This bidirectional signal is used for data on the slave SMBus.
