Port group 6: pin functions and port types
Port group 6 is an 8-bit port group. In alternative mode, it comprises pins for
the following functions:
• Timer TMP0 to TMP3 channels (TIP00 to TIP31, TOP00 to TOP31)
• Timer TMG2 channels (TIG20 to TIG25, TOG21 to TOG24)
• LCD controller segment signal output (SEG12 to SEG19) (µPD70(F)3420,
• I
Port group 6 includes the following pins:
1.

For pins that support only one alternative output mode, the PFCnm bit is
not available.
Alternative input functions of I
each. Thus you can select on which pin the alternative function should
appear. If alternative functions SDA0/SCL0 are used at P64/65 make sure
to set also PFSR0.PFSR04 = 1.
Refer to “Alternative input selection“ on page 50.
