Port group 3: pin functions and port types
Port group 3 is an 8-bit port group. In alternative mode, it comprises pins for
the following functions:
• UARTA0 transmit/receive data (TXDA0, RXDA0)
• UARTA1 transmit/receive data (TXDA1, RXDA1)
• I
• LCD controller segment signal output (SEG8 to SEG11, SEG29, SEG31)
• Timer TMG2 channels (TIG21 to TIG24, TOG21 to TOG24)
• Timer TMP0 to TMP3 channels (TOP01 to TOP31) (µPD70F3424,
Port group 3 includes the following pins:

For pins that support only one alternative output mode, the PFCnm bit is
not available.

each. Thus you can select on which pin the alternative function should
appear. If alternative functions SDA1/SCL1 are used at P30/31 make sure
to set also PFSR0.PFSR05 = 1.
Refer to “Alternative input selection“ on page 50.
