Do Not Enter

Note 12. Changing setting of the A4~A0 pins is prohibited when the CSB pin= “L” (during command input).

Note 13.

1. Normal Command: when the CSB pin is set “H” after executing a command, the state of the LED lighting

reflects the PWM gradation data configured by the command.

2. Unreflected Command: when the CSB pin is set “H” after executing a command, the state of LED

lighting does not reflect the PWM gradation data configured by the command. LED lighting is not

changed by executing the command.

3. Latch Command: Latch Command simultaneously executes the LED lighting based on all the PWM

gradation data in the IC when the CSB pin is set “H” after executing the Latch command.

4. When the latch command is executed, LEDs that are not set with PWM gradation data are turned off.

5. In case of the latch command, the CSB pin can be set “H” after entering the “4-bit” instruction.

6. When ALL= “0” is set, the PWM gradation data should be set for 1-RGB (=3 LED lines).

e.g. In the case of ch3~ch0= “0011”, (R3D7~R3D0) (G3D7~G3D0) (B3D7~B3D0) should be set with

the same command.

7. When ALL= “0” is set, there is a possibility that the AP4201 becomes shipping test status by setting a one

LED line address to the “setting prohibited status” twice continuously. (It is necessary to supply the

power again to recover from this shipping test status.)
