3.3 Pullups and pulldowns
Weak pullups are provided on all GPIO pins. Pullups for TDO and TDI are not included on the CommModule
MBP and must be included on the application base board (pullup to Pin 7 of CommModule MBP).
RXD7_P92: internal pulldown 33k
3.4 Flash programming and debugging interface
The following signals of the microcontroller are required for flash programming.
See the commModule MBP Evaluation Kit manual for details. The usage of this interface is detailed in
document "E1/E20 Emulator – additional document for User’s Manual (RX User System Design) from
Renesas".

CAUTION
The memory blocks are reserved for the firmware. They must not be modified as this will
invalidate the software license and damage the commModule MBP. Only programming project
files provided by Softing shall be used to reprogram the module.
3.5 Fault Disconnect Equipment
External fault disconnect equipment (FDE) can be optionally added using the assigned FDE pins.
If not in use, connect signal FDE_PO to FDE_PI and signal FDE_NO to FDE_NI.
3.6 Simulate enable
Fieldbus conformance testing requires switching the application to simulation mode.
Simulation mode is enabled by signaling low on pin SIM_EN_P31.
For the registration of the final device by the FieldComm Group this signal must be accessible to the
fieldbus testing personnel.
