嗨，乔治，
在从FIFO模式下，PA4和PA5默认为FIFOADR线路。因此，为了使用PA4和PA5作为FIFOADR线路，您只需要在从FIFO模式中配置FX2LP。一旦在奴隶FIFO模式下，您可以在PA0／1引脚的功能之间进行选择。它可以被用作GPIO或INT引脚。为了将它们用作int引脚，相应地设置了PATAcFG.0／PATAcFFG 1。
也就是说，可以使用PA0／1作为INT引脚，PA4／5可以作为FIFOADR线。为此，设置应如下：
IFCONFIG [ 0∶1 ]＝11
PoATACFG〔0〕＝1
PoATACFG〔1〕＝1
当做，

Hi George,
In Slave FIFO mode, PA4 and PA5 by default act as FIFOADR lines. Thus, in order to use PA4 & PA5 as FIFOADR lines, you just need to configure FX2LP in Slave FIFO mode. Once in Slave FIFO mode, you can select between the functions of PA0/1 pins. It can either be used as GPIO or INT pins. In order to use them as INT pins set PORTACFG.0/PORTACFG.1 accordingly.
i.e. It is possible to use PA0/1 as INT pins, and PA4/5 as FIFOADR lines. For that the settings should be as follows:
IFCONFIG[0:1] = 11
PORTACFG[0] = 1
PORTACFG[1] = 1
