Setting the PWM gray scale counter
STP1612PW05 provides a 12-bit or 16-bit PWM color depth. Each serial data input will be
implemented according to the e-PWM algorithm.
PWM data synchronization
STP1612PW05 defines the different counting algorithms that support e-PWM, technology,
(scrambled PWM). With e-PWM, the total PWM cycles can be broken down into MSB (most
significant bits) and LSB (least significant bits) of gray scale cycles, and the MSB
information can be dithered across many refresh cycles to achieve overall same high bit
resolution. STP1612PW05 also allows changing different counting algorithms and provides
the best output linearity when there are fewer transitions of output.
