Signal
Type
Name/Description
MSMBADDR[4:1]
I
Master SMBus Address. These pins determine the SMBus address of the
serial EEPROM from which configuration information is loaded.
MSMBCLK
I/O
Master SMBus Clock. This bidirectional signal is used to synchronize
transfers on the master SMBus.
MSMBDAT
I/O
Master SMBus Data. This bidirectional signal is used for data on the mas-
ter SMBus.
SSMBADDR[5,3:1]
I
Slave SMBus Address. These pins determine the SMBus address to
which the slave SMBus interface responds.
SSMBCLK
I/O
Slave SMBus Clock. This bidirectional signal is used to synchronize trans-
fers on the slave SMBus.
SSMBDAT
I/O
Slave SMBus Data. This bidirectional signal is used for data on the slave
SMBus.
