16-bit I 2 C-bus LED driver with programmable blink rates
6.3.7 LS0 to LS3 - LED selector registers
The LSn LED select registers determine the source of the LED data.
00 = output is set LOW (LED on)
01 = output is set high-impedance (LED off; default)
10 = output blinks at PWM0 rate
11 = output blinks at PWM1 rate
