... During the IS31FL3218 acknowledge of receiving the data byte, the internal address pointer will increment by one. The next data byte sent to IS31FL3218 will be placed in the new address, and so on. The auto increment of the address will continue as long as data continues to be written to IS31FL3218 (Figure 5) ...

... A write operation of any 8-bit value to the Update Register is required to update the registers (01h~15h). 17h Reset Register Once user writes any 8-bit data to the Reset Register, IS31FL3218 will reset all registers to default value. On initial power-up, the IS31FL3218 registers are reset to their default values for a blank display. 8 ...

... Gamma correction, also known as gamma compression or encoding, is used to encode linear luminance to match the non-linear characteristics of display. Since the IS31FL3218 can modulate the brightness of the LEDs with 256 steps, a gamma correction function can be applied when computing each subsequent LED intensity setting such that the changes in brightness matches the human eye's brightness curve ...
