If I have an FX2LP in "ports" mode (IFCONFIG[1:0] = 00), can I programmatically control the CTL1 & CTL2 pins? Or are those pins only accessible in slave-FIFO and GPIF modes?
Never mind, I found the answer; the register is GPIFIDLECTL, which I had ignored because I assumed it was only relevant to GPIF mode. But it works fine in ports mode too. Sorry for the noise.
