AI[2:0] = 110 is used when the LED drivers must be globally programmed with different settings during the same
I2C bus communication, for example, global brightness or blinking change.
AI[2:0] = 111 is used when individually and global changes must be performed during the same I2C bus
communication, for example, changing color and global brightness at the same time.
Only the 5 least significant bits D[4:0] are affected by the AI[2:0] bits.
When Control register is written, the register entry point determined by D[4:0] is the first register that will be
addressed (read or write operation), and can be anywhere between 0 0000 and 1 0001 (as defined in Table 2).
When AI[2] = 1, the Auto-Increment flag is set and the rollover value at which the point where the register
increment stops and goes to the next one is determined by AI[2:0]. See Table 1 for rollover values. For example,
if the Control register = 1110 1100 (ECh), then the register addressing sequence will be (in hex):
04 11 02 ... 11 02 … as long as the master keeps sending or reading data.
