Chapter 8. Support
Not Connected
5V Supply. Connected to ADS’s 5V VCC plane. Provided as power
supply for external tool.
Digital Ground. Connected to main GND plane of the ADS.
Buffered System Clock..
Digital Ground. Connected to main GND plane of the ADS.
Buffered Tool Chip Select 1 (L). This is a buffered PowerQUICC II’s
CS6# line, reserved for an external tool.
Buffered Tool Chip Select 2 (L). This is a buffered PowerQUICC II’s
CS7# line, reserved for an external tool.
Digital Ground. Connected to main GND plane of the ADS.
ATM Port Enable (L). This line enables the ATM port UNI’s output
lines towards the PowerQUICC II. An external tool, using the same
pins as does the ATM port should consult this signal before driving
the same lines. Failure to do so might result in permanent
damage to the PM5384 ATM UNI.
ATM Port Reset (L). This signal resets the ATM UNI (PM5384). An
external tool may use this signal to its benefit.
Ethernet Port Reset (L). This signal resets the DM9161 Ethernet
transceiver. An external tool may use this signal to its benefit.
PowerQUICC II’s Hard Reset (L). When asserted by an external
H/W, generates Hard-Reset sequence for the PowerQUICC II.
During that sequence, asserted by the PowerQUICC II for 512
system clocks. Pulled Up on the ADS using a 1KΩ resistor.
When driven by an external tool, MUST be driven with an Open
Drain gate. Failure to do so might result in permanent damage
to the PowerQUICC II and / or to ADS logic.
Interrupt Request 6 (L). Connected to PowerQUICC II‘s
DP6/CSE0/IRQ6# signal. Pulled up on the ADS with a 10 KΩ
resistor. This line is shared with the ATM UNI’s interrupt line and
therefore, when driven by an external tool, MUST be driven with
an Open Drain gate. Failure to do so may result in permanent
damage to the PowerQUICC II or to ADS logic.
