Hi everybody,
the XMC4500 errata-sheet states an errata for Pins 4 and 5 of Port15. The corresponding bits in the PDISC-register cannot be written to 1. For the case of this bit being 0 the reference manual says: "Digital Pad input is enabled. Analog and digital input path active". So, doesn't this mean I could use the corresponding pins as digital input or analog input? However, the errata-sheet says "Software that reads P15_IN will read undefined values for P15_IN[4,5]"...so it seems to be bad to use the affected Pins as digital input? Any clarification about what I can do and what I can't do with these Pins would be appreciated.
Regards,
Niclas
