Hello,

 

What does RISC_ GPIO[x] mean in the "QUICC Engine Multiplex Options" table?

As the below table said, CE_PA24 has a sub-functionality named as RISC_CPIO[4]? what does it mean?

In the beginning, I think it means that CE_PA24 can be used as GPIO. But I also do a test by using CE_PA22,

although it does not have the GPIO sub-functionality, but it still can be used as GPIO, can output/input value.

 

So could you please help to clarify it?

 

 

Thank you,

Carl
