• Manufacturer: Renesas Electronics America
• Type: MCUr

Specifications of YRDKSH7216

• Design Resources: RDK for SH7216 Schematics
• Contents: Board, Cable, Documentation, Power Supply
• For Use With/related Products: SH7216
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

This RDK supports all modes except Modes 0 and 1. The most commonly used modes are Single Chip Mode (Mode 3),
USB Boot Mode (Mode 7), and SC (Single Chip) User Program Mode (Mode 7). The modes are selected using SW1.
FWE (Flash Write Enable) select is located on switch 1, MD0 is located on switch 2, and MD1 is located on switch 3.
Placing the switch in the ‘On’ position sets the value to a logic ‘0’, and the ‘Off’ position sets the value to a logic ‘1’. The
base configurations should only be set when the RDK is powered off. Toggling the FWE from ON to OFF when the RDK
is powered on will cause the 7216 to enter the single chip User Program Mode. The details of programming the FLASH
memory are described in the SH7216 Group Hardware Manual.
The RDK can also be placed into either Debug Mode or Run Mode via switch 4 on SW1. Placing the switch in the ‘OFF’
position selects Debug mode, the ‘ON’ position selects the default Run mode.
