RXD

I

UART Serial Receive Data

TXD

O

UART Serial Transmit Data

RESET

TCK

I

Processor Reset. Resets the ADSP-2196 to a known state and begins execution at the program

memory location specified by the hardware reset vector address. The RESET input must be

asserted (low) at power-up. The RESET pin has a 85 kΩ internal pull-up resistor.

I

Test Clock (JTAG). Provides a clock for JTAG boundary scan. The TCK pin has a 85 kΩ

internal pull-up resistor.

TMS

I

Test Mode Select (JTAG). Used to control the test state machine. The TMS pin has a 85 kΩ

internal pull-up resistor.

TDI

TDO

I

Test Data Input (JTAG). Provides serial data for the boundary scan logic. The TDI pin has

a 85 kΩ internal pull-up resistor.

O

Test Data Output (JTAG). Serial scan output of the boundary scan path.

TRST

I

Test Reset (JTAG). Resets the test state machine. TRST must be asserted (pulsed low) after

power-up or held low for proper operation of the ADSP-2196. The TRST pin has a 65 kΩ

internal pull-down resistor.

EMU

O

Emulation Status (JTAG). Must be connected to the ADSP-2196 emulator target board

connector only.

VDDINT

VDDEXT

GND

P

Core Power Supply. Nominally 2.5 V dc and supplies the DSP’s core processor. (four pins).

P

I/O Power Supply; Nominally 3.3 V dc. (nine pins).

G

Power Supply Return. (twelve pins).

NC

Do Not Connect. Reserved pins that must be left open and unconnected.
