Note the following characteristics of this protocol:
D Left channel is received when LRCLK is high.
D Right channel is received when LRCLK is low.
D SDIN is sampled at the rising edge of SCLK.

PWM Outputs
Designed to be used with the TAS5110 family of H-bridges, the PWM outputs provide differential 3.3-V square-wave
signals. During normal operation these outputs represent the input PCM audio in the pulse-width modulation scheme.
In the hard-mute state the P outputs (PWM_AP_L, PWM_BP_L, PWM_AP_R, and PWM_BP_R) are held low and
the M outputs (PWM_AM_L, PWM_BM_L, PWM_AM_R, and PWM_BM_R) are held high. In the quiet-mute state
the differential PWM outputs have a 50% duty cycle.
