System stop disables the ACK function and ignored commands will not have an ACK-pulse (e.g., CPU in stop or wait mode).
The GO_UNTIL command will not get an Acknowledge if CPU executes the wait or stop instruction before the “UNTIL”
condition (BDM active again) is reached (see

Increment X index register by 2 (X = X + 2), then write word to location
pointed to by X.
Write program counter.
Write D accumulator.
Write X index register.
Write Y index register.
Write stack pointer.
Go to user program. If enabled, ACK will occur when leaving active
background mode.
Go to user program. If enabled, ACK will occur upon returning to active
background mode.
Execute one user instruction then return to active BDM. If enabled,
ACK will occur upon returning to active background mode.
(Previous enable tagging and go to user program.)
This command will be deprecated and should not be used anymore.
Opcode will be executed as a GO command.
