PCI Master Prefetch Decode Policy.
Select.
0: Use field [18:16].
1: Use field [22:20].
Fixed Read Prefetch Policy.
000: None. Each read takes a complete trip to memory.
001: Initial read 08 bytes. Read next 8 only when requested.
010: Initial read 16 bytes. Read next 16 only when requested.
011: Initial read 32 bytes. Read next 32 only when requested.

Reserved. Read as written.
USB Low Power Enable. When 0, the transceiver is prevented from entering the low
power Suspend state. This bit has no functional impact on the transceiver or USB Con-
troller. Defaults to 1 (i.e., Suspend allowed).
USB Glitch Fix Enable: When 0, enable transceiver de-glitch logic. This logic sup-
presses a glitch that can occur when:
1)
and
2)
Defaults to 1 (i.e., no glitch suppression).
Note that this bit represents a deviation from the standard MSR_CONFIG register in
Section 4.8.2 "MSR Address 1: Master Configuration" on page 74.

USBC_GLD_MSR_CONFIG Bit Descriptions
The transceiver moves from the suspend state to any other state.
A low speed device is connected. The state is defined by HcControl[7:6].
