C Structure with Bit Fields: Understanding 'OutsideRelay', 'InvWork', and More

This code snippet defines a structure with several bit fields. The first field 'OutsideRelay' is a 1-bit field, followed by 'InvWork' and 'InvWorkFinal' which are 2-bit fields each. The last field 'RelayGpioEnable' is a 1-bit field.

Bit fields allow for more efficient use of memory by packing multiple variables into a single memory location. However, they can also be more difficult to work with and may not be portable across different platforms.
