Chapter 3. Power Supply 3.1. Requirements This Renesas Starter Kit operates from a 3V to 5V power supply. A diode provides reverse polarity protection only if a current limiting power supply is used. All Renesas Starter Kit boards are supplied with an E8a debugger. This product is able to power the Renesas Starter Kit board with up to 300mA. When the Renesas Starter Kit is connected to another system then that system should supply power to the Renesas Starter Kit. All Renesas Starter Ki

The Reset circuit operates by latching the state of the boot switch on pressing the reset button. This control is subsequently used to modify the mode pin states as required. The MODE pin should change state only while the reset signal is active to avoid possible device damage. The reset is held in the active state for a fixed period by a pair of resistors and a capacitor. Please check the reset requirements carefully to ensure the reset circuit on the customers’ board meets all the reset
