GENERAL PURPOSE INPUT/OUTPUT (GPIO)
General-purpose input/output pins can be used to control and respond to various
Digital
commands. They may be configured to be the input signals for the corresponding
GPI0[1:0] 27,28 Input/Output,
GPOs on the serializer or they may be configured to be outputs to follow local register
LVCMOS
settings.
General purpose input/output pins GPO[2:3] can be configured to be input signals for
Digital GPOs on the Serializer. In addition they can also be configured to be outputs to follow
GPIO[3:2] 25,26 Input/Output the local register settings. When the SerDes chipsets are working with an external
LVCMOS oscillator, these pins can be configured only to be outputs to follow the local register
settings.
