I/O Space Indicator
R/W:000000
R:01
This is the PCI I/O space base address for the Operation registers.
Bits 1:0 — I/O Space Indicator
These bits always read back ‘01’, indicating that this Base Address register defines a PCI I/O
space.
Bits 31:2 — Controller I/O Base Address
This field specifies the I/O-mapped register space of the CL-PD6833. The Operation registers
can be accessed through this window only after these bits are set to a non-zero value. The
allowable range is anywhere in the I/O map. For legacy software, this register should be set to
‘000003E1h’.
