Port group 2 is an 8-bit port group. In alternative mode, it comprises pins for
the following functions:
• Timer TMG0 to TMG1 channels (TIG02 to TIG04, TIG11 to TIG14)
• I
• LCD controller segment signal output (SEG0 to SEG7) (µPD70(F)3420,
Port group 2 includes the following pins:

Alternative input functions of I
each. Thus you can select on which pin the alternative function should appear.
If alternative functions SDA1/SCL1 are used at P20/21 make sure to set also
PFSR0.PFSR05 = 0.
Refer to “Alternative input selection“ on page 50.
Port group 2: Configuration registers
All 8-bit registers can be accessed in 8-bit or 1-bit units.
