word accumulator.
Gate the content of
word accumulator
and word W4 with
OR NOT.

result to word W8.
December 2001
Syntax: ON (OR NOT)
Operands: B, W, D, K
Action:
Gate the contents of the word accumulator and the operand with OR NOT. In
accordance with the different sizes of operand (B = 8 bit; W = 16 bit; D = K =
32 bit), 8, 16 or 32 bits will be 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 TNC saves the result of the operation in the word
accumulator.
Example:
Gate the content of words W4 and W6 with OR NOT, and assign the result to
word W8.
Initial state:
Word W4 = 36 AA (hex)
Word W6 = 3C 36 (hex)
Word W8 = ?
