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.
Double box indicates support for the Mk II mode only. Other areas indicate support for the Mk I mode only.
