NC
No Connect.
Can be left unconnected.
System Signals
74
Clk
I
System Clock (25 MHz nominal)
. In the MT90221, this clock is used for all
internal operations of the device.
76
Test1
I
Test1.
This signal should be pulled up for normal operation.
54
Reset
I
System Reset.
This is an active low input signal. It causes the device to enter the
initial state. The Clk signal must be active to reset the internal registers.
72
TCK
I
JTAG Test Clock.
It should be pulled down if not used
71
TMS
I
JTAG Test Mode Select
. TMS is sampled on the rising edge of TCK. TMS has an
internal pull- up resistor.
70
TDI
I
JTAG Test Data Input
.
68
TDO
O
JTAG Test Data Output
.
Note:
TDO is tristated by TMS pin.
69
TRST
I
TAG Test Reset
(active low). Should be asserted LOW on power-up and during
reset. Must be HIGH for JTAG boundary-scan operation.
Note:
This pin has an
internal
pull-down
.
77
Test2
I
Test2
. It should be pulled down for normal operation.
153
Test3
I
Test3
. It should be pulled down for normal operation.
152
Test4
I
Test4
. It should be pulled up for normal operation.
