IRS
Output voltage regulator pin. When “IRS=H”, this pin is NC, when
“IRS=L”, connect a regulation resistance between VSS and V5.
MPU interface select pin, “H”: 6800 MPU interface, “L”:8080 MPU
interface. When “P/S=L”, this pin fixed to “H” or “L”.
Parallel/serial data input select.
“H”: Parallel data input; “L”: Serial data input.
Power control pin for power supply circuit.
“H”: normal mode; “L”: high power mode.
V5 voltage level adjustment resistor select.
“H”: internal resistor use, L”: external resistor use by VR pin.
DC/DC voltage converter. Connect a capacitor between this pin and
CAP2-.
DC/DC voltage converter. Connect a capacitor between this pin and
CAP2+.
DC/DC voltage converter. When use 5-times voltage converter, connect a
capacitor between this pin and CAP2-.
Internal-output VREG power supply for LCD power supply, normal is
NC.
This is multi-level power supply for liquid crystal driver, and must
maintain the relative
magnitudes shown below:
