Port group 10 is an 8-bit port group. In alternative mode, it comprises pins for
the following functions:
• Timer TMP0 and TMP2 (TOP00/01, TOP20/21, TIP00)
• LCD Bus Interface read/write strobe (DBRD, DBWR)
• LCD controller segment signal output (SEG32 to SEG35) (µPD70(F)3420,
• Clocked Serial Interface CSIB0 data/clock line (SIB0, SOB0, SCKB0)
Port group 10 includes the following pins:
Port group 9: pin functions and port types
Alternative input functions of CSIB0 are provided on two pins each. Thus you
can select on which pin the alternative function should appear.
Refer to “Alternative input selection“ on page 50.
Port group 10: configuration registers
All 8-bit registers can be accessed in 8-bit or 1-bit units.
