NCP1840
Step 6. Read back the LED1 PWM Register value.
6.1 Set the part address to 1B (hex).
6.2 Set the Read/Write bit to 0.
6.3 Set the Controls Bits to 001 in order to perform a Read operation.
6.4 Set the Register Address to 08 (hex) in order to read LED1 PWM Register.
6.5 Issue another Start and set the part address to 1B (hex).
6.6 Set the Read/Write bit to 1.
Note: After this step, the NCP1840 will transmit the LED1 PWM Register data byte which should be 20 (hex).

LAYOUT CONSIDERATIONS
Some key layout guidelines are as follows:
1. The NCP1840 requires a low ? inductance ground.
2. Connect Pin 6 and Pin 15 to the “ground pad” of the NCP1840’s package ? see Figure 15.
3. Place vias on the “ground pad,” connecting the GND of the NCP1840 directly to the PCB ground plane ? see
Figure 15.
