NOTES ON CORRECT USE

• No internal resistor is connected to input pins CTL1 (pin 4), CTL2 (pin 13), CTL3 (pin 5), and CTL4 (pin 12).

When using the µPD16874, therefore, be sure to set the voltage level of these input pins to “H” or “L”.

• Keep the IN pins (pins 1 and 8) at the same potential.

• Supply a voltage lower than that supplied to the IN pins (pins 1and 8) to VDDC (pin 9).

• FLG1 (pin 3), FLG2 (pin 14), FLG3 (pin 6), and FLG4 (pin 11) are internally pulled up to VDDC (USB controller

supply voltage) (resistance: approx. 400 kΩ). Therefore, no external pull-up resistor has to be connected to

these pins.
