CHAPTER 3 OPERATING THE EMULATOR

3.4User Port Power Supply Switching

Select a user port power supply for the evaluation MCU.

■Switching of the user port power supply

CAUTION

Make sure that power to the product is turned off and the power plug is

Prohibition disconnected from outlets before handling jumpers. Doing so may result in device problems or electric shock.

On the emulator, use the jumper for switching the user port power supply to set the reference voltage of the user data bus probing circuit.

The user data bus for which the reference voltage is set corresponds to user ports 0 and 1. Set the user port reference voltage for each port power supply source.

For details on the user data bus probing circuit, see Section 3.6 "User Data Bus Switching."

UVCC1: Main power supply for the evaluation MCU

UVCC2: Secondary power supply for the evaluation MCU

Table 3.4-1"Settings of the jumper for switching the user port power supply" lists settings of the jumper for switching the user port power supply.

Table 3.4-1 Settings of the jumper for switching the user port power supply

User system			VCC SEL setting

*1: See Figure 3.3-1"Emulator-dedicated power supply switching jumper" for positions of the jumper for switching the user port power supply.

*2: Set a jumper connection to select the VCC that corresponds to a user port power supply.

Example: User port 0 power supply is UVCC1, and user port 1 power supply is UVCC2:

Jumper for selecting user port 0 power supply (P0V): Connect A to B (UVCC1 setting).

Jumper for selecting user port 1 power supply (P1V): Connect B to C (UVCC2 setting).
