Type

Pin Name

Signal Name

Input/Output Description

Serial interface TXD0–TXD5 Transmit data

Output

Transmit data output pin for serial interface.

RXD0–RXD5 Received data

Input

Received data input pin for serial interface.

Real-time

RTDTXD

RTD transmit data

Output

debugger

RTDRXD

RTD received data

Input

Serial data input pin for the real-time debugger.

(RTD)

RTDCLK

RTD clock input

Input

Serial data transmit/receive clock input pin for the real-time

debugger.

RTDACK

RTD acknowledge

Output

A “L” level pulse is output from this pin synchronously with

the start clock for the real-time debugger’s serial data output

word. The “L” level pulse width indicates the type of command/

data received by the real-time debugger.

CAN

CTX0, CTX1 Transmit data

Output

This pin outputs data from the CAN module.

CRX0, CRX1 Received data

Input

This pin inputs the data for the CAN module.

JTAG

JTMS

Test mode select

Input

Test mode select input to control the state transition of the

test circuit.

JTCK

Test clock

Input

Clock input for the debug module and test circuit.

JTRST

Test reset

Input

Test reset input to initialize the test circuit asynchronously

with device operation.

JTDI

Test data input

Input

This pin inputs the test instruction code or test data that is

serially received.

JTDO

Test data output

Output

This pin outputs the test instruction code or test data serially.

NBD

NBDD0

Command/

Input/output

NBD command, address, and data input/output pins.

–NBDD3

Address/Data

NBDCLK

Synchronous clock

Input

NBD synchronous clock input pin.

input

NBDSYNC#

Top of data input

Input

Input pin to control the start position of NBD data.
