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.
