Notes 1. Before executing the IN or OUT instruction, set MBE to 0 or 1 and set MBS to 15.
2. TBR and TCALL instructions are assembler pseudo-instructions for the GETI instruction’s table definitions.
3. Shaded areas indicate support for Mk II mode only. Other areas indicate support for Mk I mode only.
