"LSB" Transmits the LSB ( L ast S ignificant B it) first.
Parallel transmission:
The LSB is transmitted on the first data line.
Example:
●
Fig. 7-24: User defined > Bit order LSB: I/Q parallel transmission, alignment
MSB, 5 bit
word size = 5
word alignment = MSB
bit order
= LSB
●
Fig. 7-25: User defined > Bit order LSB: I/Q parallel transmission, alignment
LSB, 9 bit
word size = 9
word alignment = LSB
bit order
= LSB
Serial transmission:
The LSB is transmitted first.
Example:
Fig. 7-26: User defined > Bit order LSB: I/Q serial transmission, 16 bit
word size = 16 Bit
bit order = LSB
