Description
PCI TRDY/Control Enable
Specifies the function that negates TRDY within 5
cycles before disconnection in a target access.
0: Disabled
1: Enabled
PCI Pre-Fetch Enable
Specifies whether pre-fetch is performed when a
target memory access is performed by an external
PCI device.
0: Disabled
1: Enabled
Byte Swap
Specifies whether byte data is swapped when the PCI
bus is accessed.
0: No swap
1: Byte data is swapped
Reserved
This bit is always read as 0. The write value should
always be 0.
Bus Master Arbitration
Controls the PCI bus arbitration mode of the PCIC
when the PCIC is in host mode. This bit is ignored
when the PCIC is in normal mode.
Note: For details, see section 13.4.5 (3), Arbitration.
