2.8 E10A-USB Interface 

 

The M3A-HS49 has a 36-pin H-UDI connector and 14-pin H-UDI connector included in it for connection to the 

E10A-USB. 

Because the SH7149's H-UDI pins and AUD pins are being output to the extension connector, do not use the 

applicable pins of the extension connector when debugging with the H-UDI connector. 

Figure2.8.1 shows the block diagram of E10A-USB interface.
