(3) Bit Fields
A bit field is a member allocated with a specified size in a structure, union, or class. This part
explains how bit fields are allocated.
Bit Field Members: Table 10.17 shows the specifications of bit field members.
Table 10.17 Bit Field Member Specifications
Notes: 1. To use a member of a bit field, data in the bit field is extended to the declared type.
Note: One-bit bit field data with a sign (declared with signed) is interpreted as the sign, and can

only represent 0 and -1. To represent 0 and 1, bit field data must be declared with
unsigned.
Sign extension: The most significant bit of a bit field is used as a sign and the sign is
written to all higher-order bits to extend data.
