PCI Express Configuration Register (PEX_CONFIG)
MPC8544E PowerQUICC III Integrated Host Processor Family Reference Manual, Rev. 1
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 24 ns at 333 MHz and 30 ns at 260 MHz.
Timeout period based on different TC settings:
0x000_0000
0x400_FFFF
0xFFF_FFFF 7.12 seconds at 333.33 MHz platform clock
Reserved
Sense ASPM Control. This bit controls the default value of ASPM of PEX Link Control Register’s bit 0. See
