RM57L843: GIOC and GIOD

Hi Edwin,

Actually, GIOC and GIOD are not implemented on this specific device.
As mentioned in datasheet terminal description table, only GIOA and GIOB were implemented for this device.
Writing into GIOC and GIOD has no effect in the behavior.

And also, you can refer HALCoGen:

Here also you can see that configuration is only for GIOA and GIOB. I think this TRM information is little misleading, i will note down this as a typo and will correct in future versions.

Thank you.  Yes, the TRM should indicate which devices have GIOC and GIOD.

Does this mean that the RM57L843 only has 16 general-purpose interrupt inputs available (on GIOA and GIOB)?

Yes only 16 were available.

However, in this device we can also configure other peripheral pins as GPIO.

I mentioned this procedure in below link, please go through it once:
