Changes

Writes the byte value from the source address, or the value argument itself, into the destination 8-bit bank. If the source bank '''S''' is zero, the value given by '''V''' is written directly into the destination address; otherwise, the value is retrieved from the source bank/address '''S'''/'''V''', and then written to the destination bank/address '''D'''/'''A'''. If the destination is a 16-bit bank, the high byte of the destination will remain unchanged.
