Software programmable LED group and three Sub Call I²C bus addresses allow all or defined groups of
TLC59116 devices to respond to a common I²C bus address allowing, for example, all red LEDs to be turned on
or off at the same time or a marquee chasing effect, thus minimizing I²C bus commands. Four hardware address
pins allow up to 14 devices on the same bus.
The Software Reset (SWRST) call allows the master to perform a reset of the TLC59116 through the I²C bus,
identical to the Power-On Reset (POR) that initializes the registers to their default state, causing the outputs to
be set high (LED off). This allows an easy and quick way to reconfigure all device registers to the same
condition.
