Notes 1. Setting MBE = 0 or MBE = 1, MBS = 15 is required during the execution of the IN or OUT instruction.
2. The TBR and TCALL instructions are assembler quasi-directives for the GETI instruction table definitions.
3. The sections in double boxes are only supported in the Mk II mode. The other sections are only supported in
the Mk I mode.
