Port group 9 is an 8-bit port group. In alternative mode, it comprises pins for
the following functions:
• LCD Bus Interface data lines (DBD0 to DBD7)
• LCD controller segment signal output (SEG36 to SEG39) (µPD70(F)3420,
• LCD controller common signal output (COM0 to COM4) (µPD70(F)3420,
Port group 9 includes the following pins:
Port group 9: pin functions and port types
Though DBD0-7 is a bidirectional bus PMnm must be set to "0", i.e. to output
mode, when the port is used as LCD bus I/F bus DBD0-7. The change of the
direction is performed automatically, when data is read from the external bus.
Port group 9: configuration registers
All 8-bit registers can be accessed in 8-bit or 1-bit units.
