Note 1: P221 is a CAN input-only pin.
Note 2: P222-P223 are always input/output ports (single-function pins).
Note 3: P224 and P225 have their pin functions changed depending on how the MOD0 and MOD1 pins are
set. Also, use of these ports requires caution because they have a debug event function.
Note 4: P226 and P227 are not accommodated.
