Increment Address Pointer Then Read / Write Addressed RAM or Register Location
Address Pointer Operations (no data is written or read, no pointer auto-increment)
Read / Write RAM or Register Location Using Current Address Pointer Value
Read
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 location addressed by current address pointer value in register 15
Write location addressed by current address pointer value in register 15
Read addressed location after incrementing pointer in register 15
Write addressed location after incrementing pointer in register 15
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.
