Figure 270. 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 271. MSB justified 24-bit frame length with CPOL = 0
Figure 272. MSB justified 16-bit extended to 32-bit packet frame with CPOL = 0
LSB justified standard
This standard is similar to the MSB justified standard (no difference for the 16-bit and 32-bit
full-accuracy frame formats).
