Description
Controls the assertion of S_RESET_L signal pin on the secondary
interface
0: does not force the assertion of S_RESET_L pin
1: forces the assertion of S_RESET_L
Reset to 0
Controls bridge’s ability to generate fast back-to-back transactions to
different devices on the secondary interface.
0: does not allow fast back-to-back transactions
1: enables fast back-to-back transactions
Reset to 0
Set’s the maximum number of PCI clocks the bridge will wait for an
initiator on the primary to repeat a delayed transaction request. The
counter starts right after the delayed transaction is at the front of the
queue. If the master has not repeated at least once before the counter
expires, the bridge discards the transaction from the queue.
