Detailed Description

Phase alignment structure.

This structure is used to manage phase alignment for 8-bit bytes. It contains a function pointer for fetching bytes, a pointer to the store, a carry value, and a shift count.

The fetch function pointer is used to retrieve the next byte in the phase-aligned stream, either by left shifting, right shifting, or no shifting. The store pointer points to the data being processed. The shift value indicates how many bits to shift the data. The carry value is used to hold any overflow from the previous byte fetch.
