Function
1
VDD1
I
–
3.3V core supply.
2
GND1
I
–
Core ground.
3
INT
I/O
–
External interrupt line (Input/Output). When this line is asserted low, the
DSP may be interrupted. Acts as IRQA line of DSP core.
4
SCANEN
I
–
SCAN Enable When active with TESTEN also active, controls the
shifting of the internal scan chains.
5
TESTEN
I
–
Test Enable. When active, puts the chip into test mode and muxes the
XTI clock to all flip-flops. When SCANEN is also active, the scan chain
shifting
6
DBRQN
I
–
Debug Port Request Input. Means of entering the Debug mode of
operation.
