q Pins for FLD Automatic Display
Ports P0, P1, P20–P23, P3, P8, P9, and PA is selected for the
FLD automatic display function by setting the automatic display
control bit of the FLDC mode register 2 (address 003716) to
“1”.
When using the FLD automatic display mode, set the number
of segments and digits for each port.

Setting Method
The individual bits of the segment/port switch register (address 003516) can be set each pin
to either segment (“1”) or general-purpose I/O port (“0”).
The individual bits of the segment/port switch register (address 003416) can be used to set
each pin to either segment (“1”) or general-purpose I/O port (“0”).
None (segment only)
None (segment only)
The individual bits of the segment/digit switch register (address 003216) and the bit 6, 7 of
the FLDC mode register 2 can be used to set each pin to segment (“1”) or digit (“0”). (Note)
None (digit only)
The individual bits of the digit/port switch register (address 003316) can be used to set each
pin to digit (“1”) or general-purpose output port (“0”). (Note)
Note : Be sure to set digits in sequence.
