[Description]
This is a software interrupt instruction.
PSW and the next instruction address (PC+1) are saved to the stack. After that, the IE flag is cleared (0)
and the saved data is branched to the address indicated with the word data at the vector address (003EH).
Because the IE flag is cleared (0), the subsequent maskable vectored interrupts are disabled.
The RETB instruction is used to return from the software vectored interrupt generated with this instruction.
