The user may change the interrupt status address via S1. Please note
that the address decoder will occupy a continuous, 16-byte area
related to the switch setting. For example, if you set the switch to
210H, then the address 210H to 21FH will all be decoded. The
various DIP switch settings (S1) for the interrupt status register are as
shown in the table opposite.
