ADSP-2191M
Design-for-Emulation Circuit Information
For details on target board design issues including: single
processor connections, multiprocessor scan chains, signal buff-
ering, signal termination, and emulator pod logic, see the
EE-68:
Analog Devices JTAG Emulation Technical Reference
on the Analog
Devices website (www.analog.com)—use site search on
“EE-68.” This document is updated regularly to keep pace with
improvements to emulator support.
Additional Information
This data sheet provides a general overview of the ADSP-2191M
architecture and functionality. For detailed information on the
core architecture of the ADSP-219x family, refer to the
ADSP-219x/2191 DSP Hardware Reference
. For details on the
instruction set, refer to the
ADSP-219x Instruction Set Reference
.
PIN FUNCTION DESCRIPTIONS
ADSP-2191M pin definitions are listed in
Table 7
. All
ADSP-2191M inputs are asynchronous and can be asserted
asynchronously to CLKIN (or to TCK for
TRST
).
Tie or pull unused inputs to V
DDEXT
or GND, except for
ADDR21–0, DATA15–0, PF7-0, and inputs that have internal
pull-up or pull-down resistors (
TRST
, BMODE0, BMODE1,
OPMODE, BYPASS, TCK, TMS, TDI, and
RESET
)—these
pins can be left floating. These pins have a logic-level hold circuit
that prevents input from floating internally.
The following symbols appear in the Type column of
Table
: G
= Ground, I = Input, O = Output, P = Power Supply, and T =
Three-State.
