Using RDY0 / RDY1 lines as GPIO in FX1/FX2/FX2LP
Last Updated: June 13, 2011
Can the GPIF's RDY0 pin can be used as a normal GPIO?
RDY0 / RDY1 lines can not be used as GPIO in FX1/ FX2 / FX2LP. In GPIF mode , they act as input lines and in the Slave FIFO mode, they act as SLRD and SLWR respecitvely.
