5.2.11. GENERAL PURPOSE PORT ( CSR12)
GPC
MD
Decription
Determines whether accessing CSR12<7:0> affects either the direction of each pin (input or
output) or the data of each pin(1 or 0). The interaction of this bit and CSR12<7:0> is described
in the following field.
When CSR12<8> is set the value that is written by the host to CSR12<7:0> sets the direction
of each pin to be either an input pin(1) or an output pin(0). When a hardware reset is initiated,
all gep pins become input pins.
When GPC is reset any host write access to CSR12<7:0> sets value on the pins that are
configured as output pins.
When GPC is reset any host read access to CSR12<7:0> reflects the input values on any
pins defined as input pins and output values on any pins defined as output pins.
The application of the general-purpose pins in board design should be correlated with the way
the port driver software is using it.
MD - General-Purpose Mode and Data
GPC - General-Purpose Control
The register value after reset is "FFFFFEXX"
