DESCRIPTION
0: Enable internal arbiter (if CFN_L is tied LOW)
1: Use external arbiter (if CFN_L is tied HIGH)
Reset to 0/1 according to what CFN_L is tied to
0: Broken master timeout disable
1: This bit enables the internal arbiter to count 16 PCI bus cycles while
waiting for FRAME_L to become active when a device’s PCI bus GNT is
active and the PCI bus is idle. If the broken master timeout expires, the PCI
bus GNT for the device is de-asserted.
