Table 8. Signal Functional Description (Sheet 3 of 9)
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3 kΩ to OV
3. Must pull down (recommended value is 1 kΩ)
4. If not used, must pull up (recommended value is 3 kΩ to OV
5. If not used, must pull down (recommended value is 1 kΩ)
6. Strapping input during reset; pull-up or pull-down required
