Circuit Diagram for PM Board: Incorrect pinouts

[bryn51]

The schematic diagram depicting PM Board (Sheet 1) appears to incorrectly depict pinouts for the SAMD21G device.

The pin numbering shown sequentially on the periphery of the device rectangle pins do not reflect the PINS used for pinMode commands in the firmware code.
Specifically the following errors were found:
Label: schematic PIN #. PIN Number for pinMODE
GPIO0. 21 22
GPIO1. 22 38
RX0. 28 34
TX0. 27 36
ADC0. 9 17
ADC1. 10 18
ADC2 47 19
ADC3. 3 14

I grant that the schematic PIN agrees with Microchip Datasheet DS40001882F - Page 30 and 31
however it seems that physical Pin numbering and logical PIN Numbering have a hidden scrambling
and it is far more useful to depict PIN Numbering used in actual programming code; or otherwise point to a disambiguation reference in the documentation.
