- * MACRO: Fld
- *
- * Purpose
- *    The macro "Fld" encodes a bit field, given its size and its shift value
- *    with respect to bit 0.
- *
- * Note
- *    A more intuitive way to encode bit fields would have been to use their
- *    mask. However, extracting size and shift value information from a bit
- *    field's mask is cumbersome and might break the assembler (255-character
- *    line-size limit).
- *
- * Input
- *    Size		Size of the bit field, in number of bits.
- *    Shft		Shift value of the bit field with respect to bit 0.
- *
- * Output
- *    Fld		Encoded bit field.

- *
- * Purpose

- *    the size, shift value, mask, aligned mask, and first bit of a
- *    bit field.
- *
- * Input
- *    Field		Encoded bit field (using the macro "Fld").
- *
- * Output
- *    FSize		Size of the bit field, in number of bits.
- *    FShft		Shift value of the bit field with respect to bit 0.
- *    FMsk		Mask for the bit field.
- *    FAlnMsk		Mask for the bit field, aligned on bit 0.
- *    F1stBit		First bit of the bit field.
