CONFIGURATION
Name SMBCLK SMBDATA PWRGD Type Input Drive Definition SMBus Clock Input SMBus Clock Input SMBus protocol communication. SMBus Data Input/Output 12mA SMBus Data Input/Output SMBus protocol communication. Host System Power Good This indicates that host system's power, including Core Logic chipsets, stable. Before host system's power stable, this input will tri-state output pins from OZ990 with exception Power Control pins. state PWRGD determines whether OZ990 Alternate mode when RESETN active. When MODE=1 PWRGD=0, OZ990 mode. When MODE=1 PWRGD=1, OZ990 Alternate mode. OZ990 Mode Input OZ990 modes operation: GPIO(with GPIOs available), PMU(with GPIOs available), Alternate PMU(with GPIOs available). OZ990 PMU, MODE PWRGD LOW. Alternate mode, MODE PWRGD HIGH. GPIO-only mode, MODE LOW. Refer MODE description more details. Power Control Outputs [8:5] General Purpose I/Os Pins PC[3:0]/GPIO[19:16] used Power Control outputs cold start, reset, Suspend, Wakeup regular GPIOs. Upon power OZ990 mode, PC[3:0] will default with OZ990 initially Suspend mode. default, falling edge-triggered SRBTN#/GPIO[15] (with Wakeup function), PC[3:0] will power system. subsequent trigger GPIO[15:8]'s Suspend Wakeup functions, values PC_SUSPEND[3:0] PC_WAKE[3:0] register will copied onto PC[3:0] output pins. Additionally, OZ990 provides power sequencing feature that allows different programmable values staggering time PC[3:0] outputs. PC[3:0] also programmable just like GPIO[19:16] pins with bits PCI[3:0] register input data PCO[3:0] register output data values. General Purpose SMIEVENT Fully programmable GPIOs that used variety dedicated specific functions. GPIO[0] SMIEVENT output alternate function. GPIO[0] defaults outputs mode, input Alternate GPIO modes. also programmable function either GPI[0] input, GPO[0]output, ALF[0] output, PWRON input, WAKE_DIS input, ID[0] input(in Alternate GPIO modes). When implementing ID[0] input, GPIO[0]/SMIEVENT internally latched from external pull-ups pulldowns, when RESETN LOW. values will stored permanently Register GPIO[0]/SMIEVENT then reconfigured output. Refer GPIO Config.1&2 Registers more details GPIO Config. Tables input/output selections.
