NOTE
The default LED Sub Call I²C bus address may be used as a regular I²C bus slave
address as long as the Sub Call addresses are disabled in MODE1 (default).
Software Reset I²C Bus Address
The address shown in Figure 6 is used when a reset of the TLC59116F needs to be performed by the master.
The Software Reset address (SWRST Call) must be used with R/W = 0. If R/W = 1, the TLC59116F does not
acknowledge the SWRST. See Register Definitions for more detail.

The software reset I²C bus address is reserved address and cannot be use as regular I²C bus slave address or as an
LED All-Call or LED Sub-Call address.
Figure 6. Software Reset Address
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]).

Figure 7. Control Register
When the Auto-Increment flag is set (AI2 = logic 1), the five low order bits of the Control register are
automatically incremented after a read or write. This allows the user to program the registers sequentially. Four
different types of Auto-Increment are possible, depending on AI1 and AI0 values.
