The Move Out Indirect (MVO@) instruction copies the value in the specified source register to the address contained by the specified address register. Note that if the address register specified is R4-R7 (the auto-incrementing registers), then the value in the address register will be incremented by one after the value in the source register has been stored at the designated address.
The "PSHR Rx" instruction is an alias for "MVO@ Rx, R6".
