Port group 4 is an 8-bit port group. In alternative mode, it comprises pins for
the following functions:
• Clocked Serial Interface CSIB0 data/clock line (SIB0, SOB0, SCKB0)
• Clocked Serial Interface CSIB1 data/clock line (SIB1, SOB1, SCKB1)
• LCD controller segment signal output (SEG20 to SEG22) (µPD70(F)3420,
• CAN0 transmit/receive data (CTXD0, CRXD0)
Port group 4 includes the following pins:
Port group 4: pin functions and port types
The alternative input function of CSIB0 isprovided on two pins. Thus you can
select on which pin the alternative function should appear.
Refer to “Alternative input selection“ on page 50.
Port group 4: configuration registers
All 8-bit registers can be accessed in 8-bit or 1-bit units.
