Attribute
P
3.3V Power Out. These lines are connected to the main 3.3V
plane of the MSC8101ADS, this, to provide 3.3V power where
necessary for external tool connected. The amount of current
allowed to be drawn from this power bus is found in
"Off-Board Application Maximum Current Consumption" on
page 66
-
Not Connected
P
5V Supply. Connected to ADS's 5V plane. Provided as power
supply for external tool. For allowed current draw, see
1. "Off-Board Application Maximum Current Consumption"
on page 66
P
Digital Ground. Connected to main GND plane of the ADS.
O
Buffered System Clock. This is a low skew buffered version of the
MSC8101's CLKOUT signal, to be used by an external tool.
P
Digital Ground. Connected to main GND plane of the ADS.
O
Buffered Tool Chip Select 1. This is a buffered MSC8101's CS6~
line, reserved for an external tool.
O
Buffered Tool Chip Select 2. This is a buffered MSC8101's CS7~
line, reserved for an external tool.
P
Digital Ground. Connected to main GND plane of the ADS.
O
ATM Port Enable. This line enables the ATM port UNI's output
lines towards the MSC8101. 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 PM5350 ATM UNI.
O
ATM Port Reset.This signal resets the ATM UNI (PM5350). An
external tool may use this signal to its benefit.
O
Ethernet Port Reset (L). This signal resets the LXT970 Ethernet
transceiver. An external tool may use this signal to its benefit.
I/O, O.D.
MSC8101's Hard Reset. When asserted by an external H/W,
generates Hard-Reset sequence for the MSC8101. During that
sequence, asserted by the MSC8101 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 MSC8101 and / or to ADS logic.
