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 the same color LEDs to
be turned on or off at the same time or 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.
