7. Data setting
The above mentioned luminance data Dv, brightness data Db and drive current data Dd are set using address
input pins A0 to A9 and data I/O pins D0 to D9. See the Timing Charts for the memory read/write enabled
period, and Table 1. Read/Write Switching Condition Correspondence Table for the pin setting conditions. The
address, data, XWR and XRD setup, hold and other timings should be as stated in the Electrical Characteristics.
See Tables 5. and 6. LED Driver Memory Map with respect to the memory address of each IOUT output pin
(IOUT0 to IOUT23).
The relationship between the data and the memory address is as follows.
