REGISTER FORMAT AND DESCRIPTION
The PV-1648 occupies 8 consecutive addresses of PC I/O address space. The first address or base address is
determined during installation by setting the onboard rotary address switch SW1. The registers and their
functions are listed in the following table (R = Read, W = write and Base = Base address.
