Digital
Input/Output,
LVCMOS
General-purpose input/output pins can be used to control and respond to various
commands. They may be configured to be the input signals for the corresponding
GPOs on the serializer or they may be configured to be outputs to follow local register
settings.

Digital
Input/Output
LVCMOS
General purpose input/output pins GPO[2:3] can be configured to be input signals for
GPOs on the Serializer. In addition they can also be configured to be outputs to follow
the local register settings. When the SerDes chipsets are working with an external
oscillator, these pins can be configured only to be outputs to follow the local register
settings.
