NOTES: 1. Although LOOP input is not ordinarily classifed as a controller pin, it is included in this table because its sense varies according to the controller used.

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 MC68160.

NOTE: In standby mode, the MC68160, B, C consumes less power supply current than in any

other 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 µs duration is generated.

Following a period of operation in the standby mode, the time required to insure stable

data reception is approximately 100 ms.
