Word Execution With The Or Not Command - HEIDENHAIN TNC 415 Technical Manual

Word execution with the OR NOT command

Operands: B, W, D, K
Operation:
The contents of the Word Accumulator and the contents of the operand (B, W, D, K) are gated 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 in the Accumulator is gated with bit 0 in the operand
Bit 1 in the Accumulator is gated with bit 1 in the operand and so on.
The result of the operation is stored in the Word Accumulator.
Example:
The contents of Word W4 and Word W6 are to be gated with OR NOT and the result assigned to
Word W8.
