MSB justified standard
For this standard, the WS signal is generated at the same time as the first data bit, which is
the MSBit.
Figure 218. MSB Justified 16-bit or 32-bit full-accuracy length with CPOL = 0
Data are latched on the falling edge of CK (for transmitter) and are read on the rising edge
(for the receiver).
Figure 219. MSB Justified 24-bit frame length with CPOL = 0
Figure 220. MSB Justified 16-bit extended to 32-bit packet frame with CPOL = 0
