+ *    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.
