address/auto increment. The address pointer will indicate the configuration location and
write signal writes the configuration data into the respective location.
The memory block is split into two page locations. One is for the 7-segment brightness
configuration memory and the other is for the LED (discrete) configuration memory. The
configuration memory address starts from 0x00 to 0x07. The configuration page address is
“10” and “11”.
Initial Value:

Memory page mapping
Description:
Address 0x00; page 0x10
LSB 0 – 2
→indicates the number of digits in the display
LSB3 MSB 4
→'11' is for constant brightness control for the display
→'00' is for variable brightness control for the display
→'01' is reserved
→'10' is reserved
MSB 5 – 7
→indicates constant brightness control value for all including the LED
(discrete)
Default is constant brightness control with 14/16 pulse width (for maximum brightness).
Page 0x10 - address 0x01 to 0x03 is for the variable brightness control value for 7
segments:
Table 14.
Digit address mapping
Default is constant brightness control with 14/16 pulse width.
Page0x11 - address 0x00 to 0x03 is for the variable brightness control value for LED
