• Manufacturer Part Number: xe8802
• Description: Data Acquisition Soc With 16+10 Bit Zoomingadc? Embedded Risc Controller And Lcd Driver
• Manufacturer: Semtech Corporation

Important Note:
In the actual version of the Prostart, the NFASTREAD pin is hard wired to VBAT. Nevertheless, the Prostart
can be used to program the device for both modes by (un)checking the NFASTREAD selection box in the
software loader. If the user wants to run the software programmed in the NFASTREAD=0 mode, he will
need to build his own application board which connects NFASTREAD=VSS.
4.3 Quick reference data memory register map
The data register map is given in the tables below. A more detailed description of the different registers is given in
the detailed description of the different peripherals.
The tables give the following information:
The reset source coding is given in Table 4-4-2. To get a full description of the reset sources, please refer to the
