If the pin is not actively driven by system, its input level may drift below low threshold and be recognized as a valid eSCI boot operation thus preventing CAN boot mode selection. Workaround: Always drive the eSCI RXD_A pin high during CAN serial boot mode. A external 10K pullup ...
The D-SUB 9 pin assignment is given in the following table. The cable connection to the computer is direct (1:1, no null-modem-cable). If no 9-pin cable is available, the internal connection bridges for pin 4, 6, and 8 must be set up externally. Signal RS-232 RXD TXD GND DTR ...
I've been trying to find a fault for a long time, but nothing - still RDWeb/Pages "Runtime error" respective "Object reference is not set to an object instance.". I set up debug and log and everything what I have is:1.) from web pages...
The general exception is for accesses to address ranges of the active Boot ROM, internal XRAM and code-space data (e.g., Data Flash), where fetch is always from the internal memory regardless of the status of EA pin. Most XC800 derivatives include a section for Boot ROM code, the size...

this sensor — is the output impedance of the sensor and what the ADC pin needs to see. Section 23.6.1 of the Atmel manual states: “The ADC is optimized for analog signals with an output impedance of approximately 10 kΩ or less.” Where this spec comes from is explained in the ...
