2.2 Connecting the Emulator to the User System by Using the H-UDI
Port Connector
When the H-UDI port connector is installed on the user system, refer to the recommended circuit
between the H-UDI port connector and the MCU.
It is impossible to connect the emulator to the 14-pin type connector that is recommended for the
E10A-USB emulator. The 36-pin type connector is the same as that of the E10A-USB emulator.
When designing the user system, read the E200F emulator user's manual and hardware manual for
the related device.
Table 2.1 shows the type number of the emulator, the corresponding connector type, and the use of
AUD function.
Table 2.1 Type Number, AUD Function, and Connector Type
Type Number Connector AUD Function
R0E0200F1EMU00 14-pin connector Not available
R0E0200F1EMU00 36-pin connector Available
The H-UDI port connector has the 36-pin and 14-pin types as described below. Use the 36-pin
connector when using the emulator.
1. 36-pin type (with AUD function)
The AUD trace function is supported. A large amount of trace information can be acquired in
realtime. The window trace function is also supported for acquiring memory access in the
specified range (memory access address or memory access data) by tracing.
2. 14-pin type (without AUD function)
The AUD trace function cannot be used because only the H-UDI function is supported. This
connector type is not available for the emulator. Use the E10A-USB emulator.
Notes: 1. In the R5E70855R or R5E70865R, the AUD pins (AUDCK, AUDATA3 to
AUDATA0, and _AUDSYNC) are assigned to two different pins. When the AUD
function is used, connect either of pins to the H-UDI port connector.
2. The 36-pin H-UDI port connector is required to connect the emulator. When the MCU
does not support the AUD function or the AUD function is not used, do not connect
anything to the AUD pins (AUDCK, AUDATA3 to AUDATA0, and _AUDSYNC) of
the H-UDI port connector.
