Same as with INBOX.
Modify CPU FSM: WHen in state DECODE, if INSTR = "OUTBOX", if OUBOX FIFO is full (? full == 1) then next_state <= DECODE (stay here until FIFO not full anymore)
will allow to plug a UART-TX to OUTBOX
See https://github.com/adumont/uartrx-fifo/ for a working FIFO example that could be used for OUTBOX.
