Output pulse width is at its
maximum value when input
data is FF.
The input data can be used to
control the PWM pulse width
and hence generate 256
grayscales.
Outputs are OFF when the
input data is 00.
When PI SEL = L, The PWM grayscale
controls the output pulse width.
16 × 8-bit words are transferred in
parallel.
1 word is the PWM data of each output
pulse width is set in 256 step.
PI REG2 [7:0]
→ PWM data for OUT 00.
PI REG2 [15:8]
→ PWM data for OUT 01.
