Testing and Setting Bits

This section describes the BitTst function and the BitSet and BitClr procedures. You can test a bit using BitTst and specify a bit's value using BitSet and BitClr. All three of these procedures use the reversed bit-numbering scheme described in the section "Reversed Bit-Numbering" on page 3-7.
