Address Pointer Operations (no data is written or read, no pointer auto-increment)
Add 1 to the current address pointer value in register 15
Add 2 to the current address pointer value in register 15
Add 4 to the current address pointer value in register 15
Read / Write RAM or Register Location Using Current Address Pointer Value
Read location addressed by current address pointer value in register 15
Write location addressed by current address pointer value in register 15
Increment Address Pointer Then Read / Write Addressed RAM or Register Location
Read addressed location after incrementing pointer in register 15
Write addressed location after incrementing pointer in register 15
Special Purpose Commands
Copy register 13 (current Control Word address) to address pointer in register 15, then
read the location addressed by the new pointer value (read the current Control Word)
Add 0 to the current address pointer value in register 15. Then . . .
Add 1 to the current address pointer value in register 15. Then . . .
Add 2 to the current address pointer value in register 15. Then copy value from newly
addressed location to address pointer in register 15 then read newly addressed location.
Add 0 to the current address pointer value in register 15. Then . . .
Add 1 to the current address pointer value in register 15. Then . . .
Add 2 to the current address pointer value in register 15. Then copy value from newly
addressed location to address pointer in register 15 then write newly addressed location.
Read then add 4 to the current address pointer value in register 15.
Write storage address of last-written Interrupt Address Word to the address pointer
in register 15, then read the Interrupt Address Word from the Interrupt Log buffer.
Decrement memory address pointer after read operation.
