Signal Functional Description
(Part 4 of 12)
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 (recommended value is 3k
to 3.3V, 10k
to 5V
)
3. Must pull down (recommended value is 1k
)
4. If not used, must pull up (recommended value is 3k
to 3.3V)
5. If not used, must pull down (recommended value is 1k
)
6. Strapping input during reset; pull-up or pull-down required
