PCI Express Configuration Retry Timeout Register
(PEX_CONF_RTY_TOR)
PCI Express Configuration Register (PEX_CONFIG)
0
Retry disable. This bit disables the retry of a configuration transaction that receives a CRS status response
packet.
0 Enable retry of a configuration transaction in response to receiving a CRS status response until the timeout
1 Disable retry of a configuration transaction regardless of receiving a CRS status response.
Reserved
Timeout counter. This is the value that is used to load the CRS response counter.
One TC unit is 8× the PCI Express controller clock period; that is, one TC unit is 20 ns at 400 MHz and 30 ns
at 266.66 MHz.
Timeout period based on different TC settings:
0x000_0000
0x400_FFFF
0xFFF_FFFF
