19.3 Signal Descriptions
MMC2107 – Rev. 2.0
MOTOROLA
The EBI also drives the address, size, and read/write pins during internal
data transfers, but the output enable and byte enable pins are not
asserted. To see the internal data bus on the external pins, show cycles
must be enabled.
Only internal sources can terminate internal data transfers. Chip-select
channels, external TA assertion, and external TEA assertion cannot
terminate internal data transfers.
