FUNCTIONAL DESCRIPTION
SUPER I/O REGISTERS
The address map, shown below in Table 1,
shows the addresses of the different blocks of
the Super I/O immediately after power up. The
base addresses of the FDC, IDE, serial and
parallel
ports
can
configuration registers. Some addresses are
used to access more than one register.
be

via
the
HOST PROCESSOR INTERFACE
The host processor communicates with the
FDC37C665IR through a series of read/write
registers. The port addresses for these registers
are shown in Table 1. Register access is
accomplished through programmed I/O or DMA
transfers. All registers are 8 bits wide except
the IDE data register at port 1F0H which is 16
bits wide. All host interface output buffers are
capable of sinking a minimum of 12 mA.

Note 1:
Configuration registers can only be modified in configuration mode, entered only by writing a
security code sequence to 3F0. The configuration registers can only be read in configuration
mode by accessing 3F1. Access to status registers A and B of the floppy disk is disabled in
configuration mode. Outside of configuration mode, a read of 3F0 accesses status register A
and a read of 3F1 accesses status register B of the floppy disk.
Address at power up; These addresses can be changed in the configuration setup.
Addresses 320H-323H and 3F5-3F7H for XT Mode. Selectable in configuration setup.
