0
Auto-increment for all registers. D[4:0] roll over to 0 0000 after the last register (1 1011) is accessed.

1
Auto-increment for individual brightness registers only. D[4:0] roll over to 0 0010 after the last register
(1 0001) is accessed.

0
Auto-increment for global control registers only. D[4:0] roll over to 1 0010 after the last register (1 0011) is
accessed.

1
Auto-increment for individual and global control registers only. D[4:0] roll over to 0 0010 after the last
register (1 0011) is accessed.
NOTE
Other combinations are not shown in Table 3. (AI[2:0] = 001, 010, and 011) are reserved
and must not be used for proper device operation.
AI[2:0] = 000 is used when the same register must be accessed several times during a single I²C Bus
communication, for example, changing the brightness of a single LED. Data is overwritten each time the register
is accessed during a write operation.
AI[2:0] = 100 is used when all the registers must be sequentially accessed, for example, power-up programming.
AI[2:0] = 101 is used when the four LED drivers must be individually programmed with different values during the
same I²C Bus communication, for example, changing a color setting to another color setting.
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 five least significant bits D[4:0] are affected by the AI[2:0] bits.
When the 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 1011 (as defined in Table 4).
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 3 for rollover values. For example,
if the Control register = 1111 0100 (F4h), then the register addressing sequence will be (in hex):
14 → ... → 1B → 00 → ... → 13 → 02 → ... → 13 → 02 → ... as long as the master keeps sending or reading
data.
