The ETPU_CxCR bit ETPD selects between input and output pin state.
24.5.1.1.4 Alternate condition encoding scheme
This scheme is shown in
distinct Host Service Request can be used:
1. HSR = 010 or 011, which are coded into the same Entry Points (0 to 3)
2. HSR = 100,101 or 001, which are all coded into Entry Point 4
3. HSR = 110 or 111, which are both coded into Entry Point 5
The remaining Entry Points use both channel flags for better state decoding, making this scheme better
suited for Functions which need more states and/or faster state decoding, without needing many HSRs.
