Preliminary Data Sheet
Signal Functional Descriptions
The following table provides a description of the I/O signals on the PPC405EX.
Table 6. Signal Functional Description (Sheet 1 of 7)
Notes:
1. Receiver input has hysteresis.
2. Must pull up. See “Pull-Up and Pull-Down Resistors” on page 37 for recommended termination values.
3. Must pull down. See “Pull-Up and Pull-Down Resistors” on page 37 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.
