side inserting a wait state. The 64-bit extension signals are not applicable
to the pci_mt32 and pci_t32 functions. The local side deasserts
lt_rdyn in clock cycle 7. The function shows that deasserting lt_rdyn
in clock cycle 7 suspends the local side data transfer in clock cycle 8 by
deasserting lt_dxfrn. Because the local side is unable to accept
additional data in clock cycle 8, the function deasserts trdyn in clock
cycle 8 as well, preventing PCI data from being transferred from the
master device.
