(1) R = read, W = write
(2) Default value
A 97-kHz fixed-frequency signal is used for each output. Duty cycle is controlled through 256 linear steps from
00h (0% duty cycle = LED output off) to FFh (99.6% duty cycle = LED output at maximum brightness). Applicable
to LED outputs programmed with LDRx = 10 or 11 (LEDOUT0 and LEDOUT1 registers).

duty cycle = 256
