can output digit pulses by using the
digit output set switch registers. Set the digit output set switch reg-
isters by setting as many consecutive 1s as the timing count from
P2
0
. The contents of FLD automatic display RAM for the ports that
have been selected for digit output are disabled, and the pulse
shown in Figure 59 is output automatically.
The output timing consists of Tdisp time and Toff1 time, and Toff2
time does not exist.
Because the contents of FLD automatic display RAM are dis-
abled, the segment data can be changed easily even when
segment data and digit data coexist at the same address in the
FLD automatic display RAM.
This function is effective in 16-timing
ordinary mode and 16-timing
gradation display mode. If a value is set exceeding the timing
count (FLD data pointer reload register
s set value + 1) for any
port, the output of such port is
