3 of 37 october 3, 2011 idt 89HPES22H16 data sheet figure 3 smbus interface configuration examples hot-plug interface the pes22h16 supports pci express hot-plug on each downstream port (ports 1 through 15). to reduce the number of pins required on the device, the pes22h16 utilizes an external i/o expander, such as t hat used on pc motherboards, connected to the smbus master int erface. following reset and configuration, whenever the state of a hot-plug output needs to be modified, the pes22h16 generates an smbus transact ion 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 w hich is received on the ioexpintn input pin (alternate function of gpio) of the pe s22h16. in response to an i/o expander interrupt, the pes22h16 ge nerates an smbus transaction to read the state of all of the hot-plug inputs from the i/o expander. general purpose input/output the pes22h16 provides 32 general purpose i/o (gpio) pins t hat may be individually configur ed as general purpose inputs, general purpose outputs, or alternate functions. some gpio pins are shared wi th other on-chip functions. these alternate functions may be enabl ed via software, smbus slave interface, or serial configuration eeprom. pin description the following tables lists the functions of the pins provided on the pes22h16. some of the functions listed may be multiplexed onto the same pin. the active polarity of a signal is defined using a suffix. si gnals ending with an ?n? are defined as being active, or asserted, when at a logic zero (low) level. all other signals (including clocks, buses, and select lines ) will be interpreted as being active, or asserted, when at a logic one (high) level. differ- ential signals end with a suffix ?n? or ?p.? the differential signal ending in ?p? is the positive portion of the differential pair and the differential signal ending in ?n? is the negative porti on of the differential pair. signal type name/description pe0rp[3:0] pe0rn[3:0] i pci express port 0 serial data receive. differential pci express receive pairs for port 0. port 0 is the upstream port. pe0tp[3:0] pe0tn[3:0] o pci express port 0 serial data transmit. differential pci express transmit pairs for port 0. port 0 is the upstream port. pe1rp[0] pe1rn[0] i pci express port 1 serial data receive. differential pci express receive pair for port 1. pe1tp[0] pe1tn[0] o pci express port 1 serial data transmit. differential pci express transmit pair for port 1. pe2rp[3:0] pe2rn[3:0] i pci express port 2 serial data receive. differential pci express receive pairs for port 2. pe2tp[3:0] pe2tn[3:0] o pci express port 2 serial data transmit. differential pci express transmit pairs for port 2. table 2 pci express interface pins (part 1 of 3) processor pes22h16 ssmbclk ssmbdat msmbclk msmbdat smbus master other smbus devices serial eeprom processor pes22h16 ssmbclk ssmbdat msmbclk msmbdat smbus master other smbus devices serial eeprom ... ...
