D950-Core
7.5 Emulation and Test Unit (EMU)
7.5.1 Introduction
The D950-Core EMU is a peripheral which performs functions dedicated to emulation and test
through the external IEEE 1149.1 JTAG interface.
The emulation and test operations are controlled by an off-core Test Access Port (TAP) and
an off-core emulator by means of dedicated control I/Os.

D950-Core Emulation and Test
Emulation mode can entered in two ways:
Asserting ERQ input pin low.
Meeting a valid breakpoint condition or executing an instruction in single step
mode.
Most of D950-Core instructions can be executed in emulation mode, including arithmetic/logic,
JUMP/CALL and MOVE. These instructions are used to display the processor status
(memories and registers) and restore the context.
Exiting the emulation mode is controlled by the PC-board emulator through the JTAG
interface.
