GPIO [3:1] of PI7C9X110 are defined for hot-plug usage if MSK_IN=1 during Reset. Please see configuration
register definition (offset 78h – 7Bh).
GPIO [3:0] are also defined the address bits of SMBUS device ID if SM Bus is selected (TM1=1). The address-
strapping table of SMBUS with GPIO [3:0] pins is defined in the following table:
Table 8-1 SM Bus Device ID Strapping
GPIO [3:0] pins can be further defined to serve other functions in the next generation Device.
Four GPI [3:0] and four GPO [3:0] have been added to PI7C9X110 when external arbiter is selected (CFN_L=1). If
external arbiter is selected, REQ_L [5:2] and GNT [5:2] will become the GPI [3:0] and GPO [3:0] respectively.
If Hot Plug Control is implemented thru PI7C9X110 device, the pin function of GPIO [3:0] configured in Forward
or Reverse Mode are defined as follow:
