mode. Some newer LEDs include integrated Zener diodes to limit voltage transients, reduce EMI and protect the LEDs, and these must
be driven only in the open-drain mode to prevent overheating the IC.
Change of the outputs at the STOP command allows synchronizing outputs of more than one PCA9634. Applicable to registers from
02h (PWM0) to 0Dh (LEDOUT) only.

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).
