bit field

(data)
Part of an item of data, storage location or message, identified as a certain number of contiguous bits starting at a certain bit position within the data. Bit position zero is usually the least significant bit.

For example, in an ARM machine code instruction the four-bit field at bits 28 to 31 (the four most significant bits in the 32-bit word) is the "condition code".
