GPIO, connector J5
There are 15 GPIO pins connecting the ALi M1535D+ to the J5 24 pin header. These may be
accessed via the ALi M1535D+ via the PCI Bus. Please review the ALi M1535D+ Data
sheets for more detailed information.
Table 2-17 shows the types and number of GPIO signals available to the user from the ALi
South Bridge.
Table 2-18 shows the connections from the ALi, M1535D+, GPIO signals available at the
GPIO header (J5). Please review the ALi M1535D+ Data sheets, located on the ML310
CDROM, for more detailed information.
System Management Bus (SMBus)
The System Management Bus (SMBus) host controller in the M1535D+ supports the ability
to communicate with power related devices using the SMBus protocol. It provides quick
