System-on-Chip
NOTES:
1. These pin numbers have multiplexed functions.
2. Signals preceded by ‘n’ are Active LOW.
3. Immediately after reset, pin 144 can be programmed to function as INT5, DREQ1 or both.
Preliminary data sheet
PIN NO.
Software should avoid enabling both of these functions simultaneously. Pin 144 can also be
programmed to function as nWAIT, rendering the INT5/DREQ1 choice unavailable.
