Note:

tTcyc: SCITCLK cycle.

Note 1. Must use pins that have a letter appended to their name, for instance _A, _B, _C, to indicate group membership. SCI0 is instance

_A, SCI2 and SCI3 are instance _B, SCI1 and SCI9 are instance _C, SCI4 is instance _C and RXD is only PD14.

Note 2. All pins of group membership can be used.
