Table 4 General Purpose I/O Pins (Part 1 of 2)
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 mas-
ter 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 trans-
fers on the slave SMBus.
Slave SMBus Data. This bidirectional signal is used for data on the slave
SMBus.
