(1) Differences between the emulator and MCUs

IMPORTANT

• The emulator initializes the MCU internal register to the following values. Initial-

ization starts when the power switch is turned ON or MCU is reset.

R0 = 00000000 R1 = 00000000 R2 = 00000000 R3 = 00000000 R4 = 00000000

R5 = 00000000 R6 = 00000000 R7 = 00000000 R8 = 00000000 R9 = 00000000

R10 = 00000000 R11 = 00000000 R12 = 00000000 R13 = 00000000 R14 = 00000000

R15 = 00000100 SPI = 00000100 SPU = 00000100 BPC = 00000000PC = 00000000

ACCH = xxxxxxxx ACCL = xxxxxxxx

PSW = 00000000

(2) MCU signals connected to the SDI MCU control interface connector (Section 3.2)

Pin No. Pin Direction Connected to Remarks

1 TCLK Emulator to target JTCK of MCU Clock frequency: 5 MHz

2 Vss - GND (0 V)

3 TDI Emulator to target JTDI of MCU

4 TDO Target to emulator JTDO of MCU

5 TMS Emulator to target JTMS of MCU

6 TRST Emulator to target JTRST of MCU Totem pole output on the emulator

7 DBI Emulator to target JDBI of MCU Not used when using M3218xFxxFP

8 FVCC Emulator to target SDIVCC of MCU Not used when using M3218xFxxFP

9 Vcc Target to emulator VCCE of MCU

10 RST Emulator to target System reset

Open corrector output on the emulator

(4) Other cautions and restrictions dependent on MCU model

IMPORTANT

Note on Access Prohibited Areas:

• The emulator uses the system space from H'C000 0000 to H'FFFF FFFF stipulated

in the MCU user's manual as an emulator-only area. If the system space is accessed

by the target program, operation of the emulator cannot be guaranteed. Therefore,

do not access the area H'C000 0000 through H'FFFF FFFF from the target program.

(3) Debug specifications dependent on MCU model (Section 5.1)

RAM area: Implemented by instruction replacement

ROM area: Implemented by preexecution PC breakpoints

of MCU (4 points)

Implemented by MCU's internal resources
