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.
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).

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".
Chapter 3 - Interface
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.

Electrical specifications
4.1 Protocol select
This pin is scanned during start-up.
4.2 Operating conditions
Unless otherwise noted, all specifications apply over the specified operating temperature range.
4.3 Port input and output
The communication module has the following port input and port output specification at Vcc = 3.2V± 4%.
Analog Input
The commModule MBP incorporates a 12bit-A/D converter with a reference voltage of 3.0V
Power Output:
The power budget to supply a connected system from fieldbus is limited.
It is dependent on the rated current from fieldbus, which is adjustable in software
from IN = 10mA to 26mA.
Available output power:
P
= approx. 90mW on 6V2_OUT, with I
omax
or:
P
= approx. 70mW on 3V_OUT, with I
omax
When both power outputs are used, the available power budget is between 70 and 90mW. The slew rate
is controlled. The rise time is 1.43ms. The output current is not limited on the commModule MBP.
