When instruction other than TBR and
TCALL instructions
(taddr) (taddr+1) instruction is executed.
Notes 1.
While the IN instruction and OUT instruction are being executed, MBE must be set to 0, or MBE must
be set to 1 and MBS must be set to 15.
The TBR and TCALL instructions are the table definition assembler pseudo instructions of the GETI
instruction.
The above operations in the double boxes can be performed only in the Mk II mode. The other
operations can be performed only in the Mk I mode.
