... PD2, PE2, PE7, PC7 4.2.1.1 Using the Serial Ports The receive lines on the RCM4200 serial ports do not have pull-up resistors. If you are using the serial ports without a receiver chip (for example, for RS-422, RS-232, or RS-485 serial communication), the absence of a pull-up resistor on the receive line will likely lead to line breaks being generated since line breaks are normally generated whenever the receive line is pulled low ...

... CAUTION: Power to the Prototyping Board or other boards should be disconnected when removing or installing your RCM4200 module to protect against inadvertent shorts across the pins or damage to the RCM4200 if the pins are not plugged in cor- rectly. Do not reapply power until you have verified that the RCM4200 module is plugged in correctly ...

... The actual voltage range for a signal going to the A/D converter input is also affected by the 10, 16, and 20 V/V software-programmable gains available on each channel of the ADS7870 A/D converter. Thus, you must scale the analog signal with an attenuator circuit and a software-programmable gain so that the actual input presented to the A/D converter is within the range limits of the ADS7870 A/D converter chip (- ...

... Dynamic C Function Calls 5.2.1 Digital I/O The RCM4200 was designed to interface with other systems, and so there are no drivers written specifically for the I/O. The general Dynamic C read and write functions allow you to customize the parallel I/O to meet your specific needs. For example, use WrPortI(PEDDR, & ...

... This flag is also stored in the battery-backed SRAM. When a protected variable is updated, the “inactive” copy is modified, and is made “active” only when the update is 100% complete. This assures the integrity of the data in case a reset or a power failure occurs during the update process ...

... RCM4200 as a master for cloning. An RCM4200 master will not run the appli- cation, and further debugging is not possible as long as the macro is set to 1. Any cloned RCM4200 modules will be “sterile,” meaning that they can- not be used as a master for cloning. To develop and debug an application on an RCM4200, comment out the CL_FORCE_MASTER_MODE NOTE: Instead of defining this macro is your application, you may simply add the line CL_FORCE_MASTER_MODE=1 under the Dynamic C Options > ...

... The RCM4200 uses a reset generator to reset the Rabbit 4000 microprocessor when the volt- age drops below the voltage necessary for reliable operation. The reset occurs between 2.85 V and 3.00 V, typically 2.93 V. Since the RCM4200 will operate at voltages as low as 3.0 V, exercise care when operating close to the 3.0 V minimum voltage (for example, keep the power supply as close as possible to the RCM4200) since your RCM4200 could reset unintentionally ...
