3 of 48 february 11, 2009 idt 89hpes24t3g2 data sheet as shown in figure 3, the master and slave smbuses may be used in a unified or split configurati on. in the unified configuratio n, shown in figure 3(a), the master and slave smbuses are tied together and the pes24t3g2 acts both as a smbu s master as well as a smbus slave on this bus. this requires that the smbus master or processor that has access to pes24t3g2 registers supports smbus arbitration. in some systems, this smbus master interface may be implemented using general purpose i/o pins on a processor or micro controller, and may not support smbu s arbitration. to support these systems, the pes24t3g2 may be configured to operat e in a split configuration as shown in figure 3(b). in the split configuration, the master and slave smbuses oper ate as two independent buses and thus multi-master arbitration is never required. the pes24t3g2 supports reading and wr iting of the serial eeprom on the master smbu s via the slave smbus, allowing in system pro gramming of the serial eeprom. figure 3 smbus interface configuration examples hot-plug interface the pes24t3g2 supports pci express hot-plug on each downstream port. to reduce the number of pins required on the device, the p es24t3g2 utilizes an external i/o expander, such as that used on pc mother boards, connected to the smbus mast er interface. following res et and configura- tion, whenever the state of a hot-plug out put needs to be modified, the pes24t3g2 generat es an smbus transaction to the i/o exp ander with the new value of all of the outputs. whenever a hot-plug input c hanges, the i/o expander generates an interrupt which is received o n the ioexpintn input pin (alternate function of gpio) of the pes24t3g2. in response to an i/o expander interrupt, the pes24t3g2 generates an s mbus transaction to read the state of all of the hot-plug inputs from the i/o expander. general purpose input/output the pes24t3g2 provides general purpose input/o utput (gpio) pins (7 pins in the 19mm package and 11 pins in the 27mm package) th at may be used by the system designer as bit i/o por ts. each gpio pin may be configured independent ly as an input or output through softw are control. many gpio pins are shared with other on-chip functions. these alternate functions may be enabled via software, smbus slave interface , or serial configura- tion eeprom. bit slave smbus address master smbus address 1 ssmbaddr[1] msmbaddr[1] 2 ssmbaddr[2] msmbaddr[2] 3 ssmbaddr[3] msmbaddr[3] 4 0 msmbaddr[4] 5 ssmbaddr[5] 1 61 0 71 1 table 1 master and slave smbus address assignment for 27x27mm package processor pes24t3g2 ssmbclk ssmbdat msmbclk msmbdat smbus master other smbus devices serial eeprom processor pes24t3g2 ssmbclk ssmbdat msmbclk msmbdat smbus master other smbus devices serial eeprom ... ...
