Figure 4.12 Layout of the LED

Some signals connected to the target system are emulated on the M34502T-MCU. For details, see

"6. Connection Circuit Diagram of the M34502T-MCU".

(1) Pins connected directly to the target system (2 types, 3 lines)

•P30, P31*

•VSS

(2) Pins connected to the target system via emulation circuits and other devices. (6 types, 18 lines)

•P00 to P03

•P10 to P13

•P20, P21

•D0 to D5*

• RESET

•EVDD*

(3) Pins not connected to the target system (3 types, 3 lines)

•XIN*

•XOUT

• CNVSS

*1 For 4501, 4506 and 4580 Group MCUs, the ports P30 and P31 are not connected to the target

system when the M34501T-PTC is mounted.

*2 For 4501, 4506 and 4580 Group MCUs, the ports D4 and D5 are not connected to the target system

when the M34501T-PTC is mounted.

*3 EVDD does not input the power supply from the target system, but outputs it to the target system

from the power circuit on the M34502T-MCU. The output (ON/OFF) and the power supply (3

V/5 V) of EVDD are changed by the switches SW1 and SW3 respectively.

*4 XIN is input from oscillator circuit board OSC-2 on the M34502T-MCU and cannot be input from

the oscillator circuit on the target system. To change the frequency of the system clock, use

oscillator circuit board OSC-2 (included) with other necessary parts mounted.

Figure 4.12 shows the LED layout of the M34502T-MCU. The LED lights in green when the power

is supplied.
