3 of 30 august 10, 2011 idt 89HPES10T4G2 data sheet as shown in figure 3, the master and slave smbuses may be used in a unified or split configuration. in the unified configuratio n, shown in figure 3(a), the master and slave smbuses are tied together and the pes10t4g2 acts both as a smbus master as well as a smbus slave on this bus. this requires that the smbus master or processor that has access to pes10t4g2 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 pes10t4g2 may be configured to oper ate in a split configuration as shown in figure 3(b). in the split configuration, the master and slave smbuses operat e as two independent buses and thus multi-master arbitration is never required. the pes10t4g2 supports reading and writing of the serial eeprom on the master smbus via the slave smbus, allowing in system pro gramming of the serial eeprom. figure 3 smbus interface configuration examples hot-plug interface the pes10t4g2 supports pci express hot-plug on each downstream por t. to reduce the number of pins required on the device, the p es10t4g2 utilizes an external i/o expander, such as that used on pc mother boards, connected to the smbus master interface. following res et and configura- tion, whenever the state of a hot-plug output needs to be modifi ed, the pes10t4g2 generates an smbus transaction to the i/o exp ander 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 o n the ioexpintn input pin (alternate function of gpio) of the pes10t4g2. in response to an i/o expander interrupt, the pes10t4g2 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 pes10t4g2 provides 9 general purpose input/output (gpio) pi ns that may be used by the system designer as bit i/o ports. eac h gpio pin may be configured independently as an input or output through software control. some gpio pins are shared with other on-chip fu nctions. these alternate functions may be enabled via software, smbus sl ave interface, or serial configuration eeprom. processor pes10t4g2 ssmbclk ssmbdat msmbclk msmbdat smbus master other smbus devices serial eeprom processor pes10t4g2 ssmbclk ssmbdat msmbclk msmbdat smbus master other smbus devices serial eeprom ... ...
