SMIEVENT
Fully programmable GPIOs that can be used for a variety of dedicated or specific functions. Pin GPIO[0] has
SMIEVENT output as an alternate function. GPIO[0] defaults. It is also programmable to function as GPI[0]
input, GPO[0]output, ALF[0] output, or ID[0] input. Refer to GPIO Config.1&2 Registers for more details and
GPIO Config. Tables (section 5.0) for input/output selections.

General Purpose I/O
Fully programmable GPIO that can be used for a variety of dedicated or specific functions. GPIO[1] pin defaults
as input. It is also programmable to function as GPI[1] input, GPO[1]output, ALF[1] output, or ID[1] input. Refer
to GPIO Config.1&2 Registers for more details and GPIO Config. Tables (section 5.0) for input/output
selections.

SMBALERT#
Fully programmable GPIO that can be used for a variety of dedicated or specific functions. Pin GPIO[2] defaults
as input. This pin, when programmed as an alternate function, can generate the SMBALERT# interrupt.
SMBALERT# is an interrupt service request signal to the SMBus Host which can be generated by all devices
connected to the OZ992. Pin GPIO[2]/SMBALERT# is also programmable to function as either GPI[2] input,
GPO[2] output, ALF[2] output, or ID[2] input. Refer to GPIO Config.1&2 Registers for more details and GPIO
Config. Tables (section 5.0) for I/O selections.

Fully programmable GPIOs that can be used for a variety of dedicated or specific functions. Pins GPIO[15:8]
default as inputs. Pins GPIO[15:8] as inputs are programmable to generate SMI/SMB interrupts. They are also
programmable to function as GPI[15:8] inputs, GPO[15:8] outputs. Refer to GPIO Config.1&2 Registers for
more details and GPIO Config. Tables (section 5.0) for input/output selections.
