Bank Switch Enumerations. The third (optional) operand
of the MLD, MPYA and MPYS instructions represents
whether a bank switch is set ON or OFF. To more clearly
represent this, the keywords ON and OFF are used to state

the direction of the switch. These keywords are referenced
in the instruction descriptions through the <bank switch>
