This pin indicates that the host system
’
s power, including the Core Logic chipsets, is stable. Before the host
system
’
s power is stable, this input pin will tri-state all the output pins from OZ992.

The embedded controller will signify the OZ992 when the activated SCI has been serviced. This pin is to be
used with EC master mode only.

Fully programmable GPIOs that can be used for a variety of dedicated or specific functions. Pins GPIO[17:16]
default as inputs. They are programmable to function as either GPI[17:16] inputs or GPO[17:16] outputs. Refer
to GPIO[19:16] Config.1&2 Registers for more details and GPIO Config. Tables (section 5.0) for input/output
selections.

General Purpose I/Os
Fully programmable GPIOs that can be used for a variety of dedicated or specific functions. Pins
GPIO[19:18]/TEST[1:0] default as inputs. They are programmable to function as either GPI[19:18] inputs or
GPO[19:18] outputs. Refer to GPIO[19:16] Config.1&2 Registers for more details and GPIO Config. Tables
(section 5.0) for input/output selections.
During regular usage, pull-ups of
47K
should be connected to GPIO[19:18]/TEST[1:0] to ensure the regular
OZ992 operation. Alternative uses for GPIO[19:18] are as TEST[1:0], which provide 2 proprietary OZ992 test
modes.
