Chapter 3. Power Supply 3.1. Requirements This RSK operates from a 5V power supply. A diode provides reverse polarity protection only if a current limiting power supply is used. All RSK boards are supplied with an E10A debugger. All RSK boards have an optional centre positive supply connector using a 2.0mm barrel power jack. Warning The RSK is neither under nor over voltage protected. Use a centre positive supply for this board. 3.2. Power – Up Behaviour When the RSK is purchased th

The mode pins 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 user’s board meets all the reset timing requirements. 6.9. USB port This RSK has a Full-speed (12 Mbps) USB port compliant to USB 2.0 specification. It is available as J12 on the RSK. This port allows Boot mode
