Bit Manipulation Functions for C02 Programs
|
||||
|
||||
This module contains functions to shift and rotate the bits in a byte,
|
||||
and to extract, combine, swap and duplicate nybbles in a byte.
|
||||
|
||||
At the beginning of the program use the directives
|
||||
|
||||
#include <stddef.h02>
|
||||
#include <bitlib.h02>
|
||||
|
||||
The following functions are defined:
|
||||
|
||||
r = shiftl(b,n) Shifts byte b by n bits to the left and returns
|
||||
the result in r. If n is 0, the byte is not
|
||||
shifted, and if n greater than 8, the returned
|
||||
value will be 0.
|
||||
|
||||
r = shiftr(b,n) Shifts byte b by n bits to the right and returns
|
||||
the result in r. If n is 0, the byte is not
|
||||
shifted, and if n greater than 8, the returned
|
||||
value will be 0.
|
||||
|
||||
r = rotl(b,n) Rotate byte b by n bits to the left and returns
|
||||
the result in r, with the high bit rotated into
|
||||
the low bit on each rotation. If n is 0, the
|
||||
byte is not rotated, and any value of n greater
|
||||
than 8, will return the same result as n modulo 8.
|
||||
|
||||
r = rotr(b,n) Rotate byte b by n bits to the right and returns
|
||||
the result in r, with the high bit rotated into
|
||||
the low bit on each rotation. If n is 0, the
|
||||
byte is not rotated, and any value of n greater
|
||||
than 8, will return the same result as n modulo 8.
|
||||
|
||||
b = pack(l,r); Packs the low nybbles of bytes l and r into a
|
||||
single byte, with l becoming the left (or high)
|
||||
nybble and r becoming the right (or low) nybble.
|
||||
and returns the packed byte in b.
|
||||
|
||||
l,r = unpack(b); Unpacks byte b, returning the left (or high)
|
||||
nybble in l, and the right (or low) nybble in r.
|
||||
|
||||
d = dupl(b); Duplicates the low nybble of byte b into the
|
||||
high nybble and returns the new byte in d.
|
||||
|
||||
Note: Executes function pack() with b as both
|
||||
arguments.
|
||||
|
||||
d = swap(b); Swaps the left (or high) and right (or low)
|
||||
nybbles of byte b and returns the new byte in d.
|
||||
|
||||
Note: Executes function rotl() with the arguments
|
||||
b and 4.
|
||||
|
||||
|
||||
|
||||
|
||||
c,d,e = func(a,&d); Stores the input value a and the address of d
|
||||
in memory.
|
||||
|
||||
Returns three bytes read from memory.
|
||||
|
||||
Note: Writes argument a to variable arg0,
|
||||
the address of d to variables adr0 and adr1,
|
||||
and returns the values of variables var0,
|
||||
var1, and var2.
|
||||
|
||||
Note: This library expects the following external variables to be defined:
|
||||
|
||||
temp0: Temporary Variable
