multiple SuperH devices. Typical

features of the Solution Engine

include:

• External flash for user code

• EPROM containing monitor code

• JTAG connector easily connects

to E10A on-chip emulator

• Unbuffered CPU bus connectors

provide direct connection to

address data and control lines

• Expansion slot for daughter

boards (buffered CPU bus

provides direct connection to

address data and control lines)

• I/O connectors (for SuperH

peripheral signals)

E10A-USB on-chip emulators

The E10A-USB emulators, designed

to connect with Renesas’ JTAG

on-chip debugging interfaces,

provide real-time debugging on

the target device, using the dedicated

debugging resources built into the

target microcontroller in your user

hardware. The on-chip emulators

connect to the target system via an

interface that can be used both to

debug the system and to program

the MCU’s on-chip flash memory.

E10A-USB emulators use plug-and-

play USB 2.0 compatible interfaces

for easy connection to both

notebook computers and desktop

machines. These emulators offer:

• 255 PC breakpoints

• One hardware breakpoint on

data and address

• The ability to save a record of up

to the last eight branches

• On-chip flash programming

The E10A-USB emulator is available

in two configurations:

• HS0005KCU01H (14pin H-UDI)

• HS0005KCU02H

(14pin H-UDI + 36pin AUD)

Both provide on-chip debugging via

the Renesas H-UDI (JTAG) interface.

Advanced User Debug (AUD)

Renesas’ Advanced User Debug

interface allows you to trace

real-time data out of the device

while it is running in-system.

You can configure the AUD trace to

stream source and destination

branch addresses, memory accesses

(from user-specified data buses and

“windows” in the address space)

and also source-level variables via a

special software-trace function call.

This data is compressed on-chip,

streamed out of the AUD port, and

then captured in a dedicated

trace buffer in the E10A-USB

(HS0005KCU02H model only) or

E200F (see next section).

E200F Configurable

On-Chip/In-Circuit Emulator

The E200F is an expandable

emulation system for both on-chip

and in-circuit debugging. It provides

all of the same H-UDI (JTAG) and

AUD debug features as the

E10A-USB, but with enhanced

capabilities and system expansion

with add on options.

Enhanced Capabilities

The E200F has a high-speed USB

2.0 host interface for fast debug file

download and data upload. Eight

AUD Event points allow you to halt

on a match of AUD trace data

such as branch source/destination

address, windowed memory access

and software data variable trace.

Four external probe inputs and one

external trigger output are also

included.

Performance Analysis

The E200F emulator provides three

methods of application performance

analysis:

• On-chip performance

• AUD performance analysis

• Real-time profiling

The real-time profiling method

gives execution statistics for
