Signal Functional Description (Sheet 6 of 8)
Multiplexed signals are shown in brackets following the first signal name assigned to each multiplexed ball.
Notes:
1. Receiver input has hysteresis.
2. Must pull up. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.
3. Must pull down. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.
4. If not used, must pull up.
5. If not used, must pull down.
6. Strapping input during reset; pull up or pull down as required.
7. Pull-up may be required. See “External Bus Control Signals” on page 29.
