This option provides the packing() helper function, which permits
|
|
converting bitfields between a CPU-usable representation and a
|
|
memory representation that can have any combination of these quirks:
|
|
- Is little endian (bytes are reversed within a 32-bit group)
|
|
- The least-significant 32-bit word comes first (within a 64-bit
|
|
group)
|
|
- The most significant bit of a byte is at its right (bit 0 of a
|
|
register description is numerically 2^7).
|
|
Drivers may use these helpers to match the bit indices as described
|
|
in the data sheets of the peripherals they are in control of.
