2.3.7 Interrupt Status Register
You may change the interrupt status address via SW2 or S5. Please note
the address decoder will occupy a continuous, 8-byte area related to
switch setting. For example, if you set the switch to 210H, the addresses
210H to 217H will all be decoded. The various DIP switch settings (SW2
or S5) for the interrupt status register are shown in the figure below.
