FLD controller
Figure KA-3. Segment/Digit Setting Example
FLD automatic display pins
P0 to P6 are the pins capable of automatic display output for the FLD. The FLD start operating by setting
the automatic display control bit (bit 0 at address 035016) to “1”. There is the FLD output function that
outputs RAM contents from the port every timing or the digit output function that drives the port high with
digit timing. The FLD can be displayed using the FLD output for the segments and the digit or FLD output for
the digits. When using the FLD output for the digits, be sure to write digit display patterns to the RAM in
advance. The remaining segment and digit lines can be used as general-purpose ports. Settings of each
port are shown below.

The individual bits of the digit output set register (address 035C16,
035D16) can set each pin either FLD port (“0”) or digit port (“1”).
When the pins are set for the digit port, the digit pulse output func-
tion is enabled, so the digit pulses can always be output regardless
the value of FLD automatic display RAM.
FLD exclusive use port (automatic display control bit (bit 0 of ad-
dress 035016)=“1”)
The individual bits of the FLD/port switch register (addresses
035916 to 035B16) can set each pin to either FLD port (“1”) or gen-
eral-purpose port (“0”).
The individual bits of the FLD/port switch register (address 035B16)
can set each pin to either FLD port (“1”) or general-purpose port
(“0”). The digit pulse output function turns to available, and the digit
pulse can output by setting of the FLD output set register (address
035116). The port output format is the CMOS output. When using
the port as a display pin, a driver must be installed externally.

Setting example 1
Shown below is a register setup example where only FLD output is used.
In this case, the digit display output pattern must be set in the FLD automatic
display RAM in advance.

Setting example 2
Shown below is a register setup example where both FLD output and digit waveform
output are used. In this case, because the digit display output is automatically
generated, there is no need to set the display pattern in the FLD automatic display RAM.
