MSBLSB

MSBLSB is not a formal standard acronym with a single, universal definition in computer science. In practice, it is often used as shorthand for concepts related to the ordering and range of bits within a binary value, sometimes described as “Most Significant Bit to Least Significant Bit.” The term may appear in documentation to indicate that bit processing or representation proceeds from the most significant bit down to the least significant bit, or to denote a bit range within a larger word.

Common uses include describing how data is serialized or packed, where bits are emitted or consumed in MSB-to-LSB order, or specifying the bit positions that form a particular field within a hardware register or data protocol. For example, a data specification might state that a field is encoded from the MSB toward the LSB, or that a range of bit indices from MSB to LSB defines the field.

Because MSBLSB is not widely standardized, its precise meaning can vary by context. Ambiguity can arise when combining data from different sources or protocols that use different bit-order conventions. To avoid misinterpretation, documentation should clearly define what MSBLSB refers to in that context: the direction of bit processing (MSB to LSB or vice versa), the inclusive bit range, and how bit indices map to numerical values.

Related concepts include endianness, bit-field layout, bit ordering, and the individual terms MSB and LSB. See also references to bitwise packing and protocol specifications for specifics on how bit order is defined in a given system.
