Port group 8 is an 8-bit port group. In alternative mode, it comprises pins for
the following functions:
• Clocked Serial Interface CSIB2 data/clock line (SIB2, SOB2, SCKB2)
• LCD controller segment signal output (SEG23 to SEG28, SEG30)
• Frequency output (FOUT)
• UARTA0 transmit/receive data (TXDA0, RXDA0)
Port group 8 includes the following pins:

(µPD70(F)3420, µPD70(F)3421, µPD70(F)3422, µPD70F3423 only)
For pins that support only one alternative output mode, the PFCnm bit is
not available.
The alternative input function of UART0 is provided on two pins. Thus you
can select on which pin the alternative function should appear.
Refer to “Alternative input selection“ on page 50.
