Signal Functional Description (Part 5 of 6)
Notes:
1. Receiver input has hysteresis.
2. Must pull up. See “Pull-up and Pull-down Resistors” on page 30 for recommended termination values.
3. Must pull down. See “Pull-up and Pull-down Resistors” on page 30 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 Peripheral Bus Control Signals” on page 31.
