Switching from Slave FIFO to GPIF for FX1/FX2LP
How long does it take in CPU instruction cycles to switch from the slave FIFO to GPIF interface?
The Slave FIFO interface to GPIF is done by simply writing to the IFCFG[1:0] bits in the IFCONFIG register. Since this is a MOVX instruction, it would take a minimum of two instruction cycles. Each instruction takes four clock cycles to execute.
