The pin function after reset depends on the reset source, that means on bit OCDM.OCDM0. Refer to “OCDM -
On-chip debug mode register“ on page 45 and to the “On-Chip Debug Unit“ on page 877.

Port group 5: pin functions and port types
Port group 5 is an 8-bit port group. In alternative mode, it comprises pins for
the following functions:
• External interrupt (INTP7) (µPD70F3424, µPD70F3425, µPD70F3426,
• Sound Generator outputs (SGO, SGOA)
• Frequency output (FOUT)
• N-Wire interface signals (DDI, DDO, DCK, DMS)
• CAN1 transmit/receive data (CTXD1, CRXD1)
• UARTA1 transmit/receive data (TXDA1, RXDA1)
Port group 5 includes the following pins:
1.
2.
3.

µPD70F3427 only)
For pins that support only one alternative output mode, the PFCnm bit is
not available.
The setting of bit OCDM.OCDM0 applies only to pins of port type R.
The alternative input function of UARTA1 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.
