PC = [int vector * 2]
This instruction allows the programmer to implement software interrupts. Int vector is multiplied by two, and zero extended to 16
bits.
The condition (cccc) bits for all of the above instructions are defined as follows.
8.19
Since Single operand instructions do not require a source field, the format of the Single operand Operation instructions is slightly
different.
Notice that the opcode field is expanded to seven bits wide. The four MSBs for all instructions of this class are “1101.”

33. Interrupt vectors 0 through 31 may be reserved for hardware interrupts, depending on the application.
34. For the JUMP mnemonics, adding an “L” to the end indicates a long or absolute jump. Adding an “S” to the end indicates a short or relative jump. If nothing is
35. For the SHR, SHL, ROR, ROL, ADDI and SUBI instructions, the three-bit count or n operand is incremented by 1 before it is used.
36. The CS5954AM QT assembler takes this into account.
