A. In this example, four TLC59116Fs are used with the same sequence sent to each.
B. ALLCALL bit in MODE1 register is equal to 1 for this example.
C. OCH bit in MODE2 register is equal to 1 for this example.

8.6.1 Control Register
Following the successful acknowledgment of the slave address, LED All Call address or LED Sub Call address,
the bus master will send a byte to the TLC59116F, which will be stored in the Control register. The lowest 5 bits
are used as a pointer to determine which register will be accessed (D[4:0]). The highest three bits are used as
Auto-Increment flag and Auto-Increment options (AI[2:0]).
