Registers
Operation of the MB86703 is controlled by values
written into registers within the device, while other reg-
isters provide device status. The register set consists
of a combination of Plug and Play standard registers
and vendor dened registers. Tables 3 and 4 are maps
of the user-accessible internal registers implemented
in the MB86703 for MEMORY and DMA modes,
respectively. In this table, a “Y” in the STD column
indicates that this is a standard PnP register and is
described in the Plug and Play ISA specication
(Appendix A). The table also provides default values
and denes, for each Plug and Play state, the type of
access available. Exceptions to the specication are
detailed in Table 5. Vendor-dened registers con-
tained in the MB86703 are described in Tables 6 to 8.
