BitSetYou can use the
BitSetprocedure to set a particular bit.
PROCEDURE BitSet (bytePtr: Ptr; bitNum: LongInt);
- A pointer to a byte in memory.
- The bit to be set, specified as a positive offset from the high-order bit of the byte pointed to by the
bytePtrparameter. The bit being set need not be in the byte pointed to by
BitSetprocedure sets (to a value of 1) the bit specified by the
SPECIAL CONSIDERATIONSThe bit-numbering scheme used by the
BitSetprocedure is the opposite of MC680x0 bit numbering. To convert an MC680x0 bit number to the format required by the
BitSetprocedure, subtract the MC680x0 bit number from the highest bit number.
SEE ALSOFor an example of the use of the
BitSetprocedure, see page 3-16. For more information about reversed bit-numbering see "Reversed Bit-Numbering" on page 3-7.
