Setting Method
The individual bits of the segment/port switch register (address 0035
16
) 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 0034
16
) 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 0032
16
) 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 0033
16
) 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.
