(1), (2) lm_req64n
This signal is not applicable to the pci_mt32 MegaCore function.
For pci_mt32, lm_req32n should be substituted for lm_req64n for 32-bit master transactions.

local side inserting a wait state. This figure applies to both the pci_mt64
and pci_mt32 functions, except the 64-bit extension signals as noted for
pci_mt32. The local side deasserts lm_rdyn in clock cycle 9.
Consequently, on the following clock cycle (clock cycle 10), the pci_mt64
and pci_mt32 functions suspend data transfer on the local side by
deasserting the lm_dxfrn signal. Because there is no data transfer on the
local side in clock cycle 10, the function suspends data transfer on the PCI
side by deasserting the irdyn signal in clock cycle 11.
