The EBI may drive the address, size, and read/write pins during internal
data transfers if show cycles is enabled, but the output enable and byte
enable pins are not asserted.
Only internal sources can terminate internal data transfers. Chip-select
channels, external TA assertion, and external TEA assertion cannot
terminate internal data transfers.
