A retry occurs before the first data phase.
A device must assert the devseln signal for at least one clock before it signals an abort.

during a PCI transaction. The PCI MegaCore function processes the PCI
signal assertion from the local side. Therefore, the PCI MegaCore
function only drives the control signals per the PCI Local Bus Specification,
Revision 3.0. The local-side application can force retry, disconnect, abort,
successful data transfer, and target wait state cycles to appear on the PCI
bus by driving the lt_rdyn, lt_discn, and lt_abortn signals to
certain values. Refer to
for more details.
When both trdyn and irdyn are active, a data word is clocked from
the sending to the receiving device
The master device should retry the current transaction
The master device should stop the current transaction
The master device should abort the current transaction
