MOV Mem[X], Reg Instruction
The Memory[X] to Register MOV copies a value from main memory to any register or counter. Any combination where the source and destination are different are acceptable. This allows the programmer to update the program counter, a general purpose register, even the stack pointer with no restrictions.
As of June, 2020, the source should be 0011 for main memory, but it is possible to copy values from the firmware or a different bank of memory so it is left variable.
