target access is valid or invalid.
When this bit is set to invalid, Writes to the I/O Space Base Address
Register of the PCI Configuration Register become invalid. Also, “0” is
returned to Reads as a response.
1: Validates I/O Space for target access.
0: Invalidates I/O Space for target access.
Byte Swap Disable
(Default: Little Endian Mode: 0x1; Big Endian Mode: 0x0) Sets the byte
swapping of the I/O Space for target access.
1: Do not perform byte swapping.
0: Perform byte swapping.
Please use the default state in most situations. If this bit is changed to “1”
when in the Big Endian Mode, the byte order of transfer to the I/O Space
through DWORD (32-bit) access will not change.
Endian Transfer
(Default: Little Endian Mode: 0x0; Big Endian Mode: 0x1) Sets the Endian
Transfer of the I/O Space for target access.
1: Performs Endian Transfer.
0: Does not perform Endian Transfer.
Please use the default state.
Base Address 2 (Default: 0x000)
Sets the G-Bus base bus address of the I/O Space for target access. Can
set the base address in 256-byte units.
