Bi-phase bit detection
The clock used for sampling the DALI signal is programmed by the DCMCLK register. Each
bit phase is sampled 16 times. The bit phase level is determined by two of three sample
clock pulses (pulses 6,7,8). The two phase levels of the bi-phase bit are shifted into the 4-bit
pre-shift register at the 9th sample clock pulse.
Only the second phase level of the bi-phase bit is shifted into the 16-bit shifter.
The 4-bit pre-shifter is used to detect any errors in the received frame.
When a change of phase is detected (edge trigger), the 4-bit sample clock counter (integer
range 0 to15) is cleared.
