LSB alignment standard
In the transmission process of LSB alignment standard, the data is changed on
the falling edge of the clock signal; in the receiving process, the data is read on
the rising edge of the clock signal. When the channel length is the same as the
data length, the LSB alignment standard is the same as the MSB alignment
standard. If the channel length is larger than the data length, the valid data of
the LSB alignment standard is aligned with the lowest bit.
