LED display circuit
(1) LED display method
For example, the following shows how the LED LP6 (APS) lights up for displaying “automatic paper
sensing”.
When DSPON0 signal becomes “L” level, transistor Q3 is turned ON. Further, when IC1 pin16 (D8)
becomes “L” level, current flows from +5VD to LP6 (APS) through the transistor. In this way LP6
(APS) lights up.
