15.9. OTHERS
15.9.1. I/O Terminal
- The Input terminal has two systems; both of them are connected to the
Input Port of the IC103 GPIO.
- Due to Internal Pull-up Resistance, the PNP Transistor (Q501, Q502) on
the following stage is usually in the OFF state and the Input Port
connected to the collector is at L level.
- If the terminal is short-circuited with the GND or the signal of L level is
input, the PNP Transistor goes ON and the Input Port goes to H level.
