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.
