Figure 2 SMBus Interface Configuration Examples
Hot-Plug Interfac e
The PES12T3G2 supports PCI Express Hot-Plug on each downstreamport. To reduce the number of pins required on the device, the PES12T3G2
utilizes an external I/O expander, such as that used on PC motherboards, connected to the SMBus master interface. Following reset and configura-
tion, whenever the state of a Hot-Plug output needs to be modified, the PES12T3G2 generates an SMBus transaction to the I/O expander with the
new value of all of the outputs. Whenever a Hot-Plug input changes, the I/O expander generates an interrupt which is received on the IOEXPINTN
input pin (alternate function of GPIO) of the PES12T3G2. In response to an I/O expander interrupt, the PES12T3G2 generates an SMBus transaction
to read the state of all of the Hot-Plug inputs fromthe I/O expander.
General Purpose Input/Output
The PES12T3G2 provides 9 General Purpose Input/Output (GPIO) pins that may be used by the systemdesigner as bit I/O ports. Each GPIO pin
may be configured independently as an input or output through software control. Some GPIO pins are shared with other on-chip functions. These
alternate functions may be enabled via software, SMBus slave interface, or serial configuration EEPROM.
