Port group 10
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,
µPD70(F)3421, µPD70(F)3422, µPD70F3423 only)
• Clocked Serial Interface CSIB0 data/clock line (SIB0, SOB0, SCKB0)
Port group 10 includes the following pins:
Note
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
.
Access
All 8-bit registers can be accessed in 8-bit or 1-bit units.
