Figure 10.4.12 G2P Timeout Count Register
Retry Time Out (Default: 0x80)
Sets the maximum number of retries to accept when operating as the
initiator on the PCI Bus. Ends with an error when receiving more retry
terminations than the set maximum number.
Setting a “0” disables this timeout function.
Note: Generally, disable retry time-out detection by setting this field to zero.
TRDY Time Out (Default: 0x80)
Sets the maximum value of the time to wait for assertion of the TRDY*
signal when operating as the initiator on the PCI Bus.
Setting a “0” disables this timeout function.
Note: Generally, disable TRDY time-out detection by setting this field to
Some PCI devices invoke more than 128 retries at normal times.
zero. Some PCI devices exhibit a TRDY delay longer than 128 PCI
clocks at normal times.
