Minimum pulse width for LEDn brightness control is 2.5 s.
Individual LED brightness control signals
Minimum pulse width for LEDn brightness control is 2.5 s.
Minimum pulse width for group dimming is 80 s.
When M = 1 (GRPPWM register value), the resulting LEDn brightness control + group dimming signal will have 2 pulses of the
LED brightness control signal (pulse width = N
with M = (1 to 16)
