The expansion interface consists of the footprints for 3 connectors.  The following 
table shows the interfaces each connector provides.  For the exact pin-out of these 
connectors refer to 

.  Analog Devices does not 

populate these connectors or provide any additional support for this interface.  
The mechanical locations of these connectors can be found in section 

P1 

5V, GND, Address, Data 

P2 

3.3V, GND, EBUI control signals, PF0-15, SPI0-1, SPORT1, 
UART0-1, TMR0-2, NMI 

P3 

1.5V, GND, Reset, USB, CLKOUT, SLEEP 

Limits to the current and to the interface speed must be taken into consideration if 
you use this interface.  The maximum current limit is dependent on the regulator 
used and its capabilities.  Additional circuitry can also add extra loading to 
signals, decreasing their maximum effective speed.   

! Analog Devices does not support and is not responsible for the effects of 

The JTAG emulation port allows an emulator to access the DSP’s internal and 
external memory through a 6-pin interface.  The JTAG emulation port of the DSP 
is also connected to the USB debugging interface (NOTE: This is not the DSP’s 
USB interface).  When an emulator is connected to the board at P8, the USB 
debugging interface is disabled.  See section 

 for more information about the 

JTAG connector.
