2. The Motorola controller interface contained in the MC68360 (QUICC ) is compatible with the AMD 7990 (LANCE ) and 79C900 (ILACC ) controllers.
3. The pin sense is shown from the perspective of the identified controller pin.
4. Supported only by MC68160A.

mode. Additionally, in the standby mode, all of the controller inputs and outputs are
driven to the high impedance state. When the standby mode is deasserted, an internal
reset pulse of approximately 6.0 s duration is generated.
Following a period of operation in the standby mode, the time required to insure stable
data reception is approximately 100 ms.
