Subtraction. Subtracts one or up to seven numbers from the input IN1 and places the

operation occurs.
5.9.1 Overflow
If an operation on integer operands results in overflow, the output value wraps around.
Examples:
▪ If the ADD operation, 32767 + 1, is performed on signed integer operands, the result is -32768
▪ If the SUB operation, -32767 – 1, is performed on signed integer operands, the result is 32767
▪ If an ADD_UINT operation is performed on 65535 + 16, the result is 15.
