6.3.1
Description: Finds absolute values. When the Sx and Sy operands are positive, the contents of the
operands are stored to the Dz operand. If the value is negative, the amounts of the Sx and Sy
operand contents are subtracted from 0 and stored in the Dz operand.
The DC bit of the DSR register are updated according to the specifications of the CS bits. The N,
Z, V, and GT bits of the DSR register are updated.
Operation:
