Word processing
with the AND NOT
command
January 2012
Syntax: AN (AND NOT)
Operands: B, W, D, K
Action:
Gate the contents of the word accumulator and the operand with AND NOT.
In accordance with the different data widths of the operands (B = 8 bits; W =
16 bits; D = K = 32 bits), 8, 16 or 32 bits, respectively, are influenced in the
accumulator. Thus, bit 0 of the accumulator is gated with bit 0 of the operand,
bit 1 of the accumulator with bit 1 of the operand, etc. The control saves the
result of the operation in the word accumulator.
Example:
Gate the content of words W4 and W6 with AND NOT, and assign the result
to word W8.
Initial state:
Word W4 = 36 AA (hex)
Word W6 = 3C 36 (hex)
Word W8 = ?
Function
Load W6 into the word
accumulator.
Gate the contents of word
accumulator and word
W4 with AND NOT.
Assign the gating result to
word W8.
