Final answer:
Override pulls likely involve changing instruction or data pathways and do not inherently result in a new row in the Memory Address Register, which stores memory addresses for access.
Step-by-step explanation:
The question whether override pulls create a row in MAR (Memory Address Register) seems to refer to a process in computer architecture or computer engineering, possibly involving CPU operations or the handling of instructions. However, without the specific context of the system or technology in use, it's difficult to give a definitive answer. Generally speaking, an override pull could be an operation that involves changing the normal flow of instructions or data pathways within a CPU or other hardware control logic, but it does not inherently imply that a new row is created in the MAR, which is typically used to hold the memory address that is being read from or written to. In most cases, changes in the MAR occur due to the processing of instructions that require access to specific memory addresses, not from an 'override pull' operation directly.
