iFix RT809F - Page 64

area blank is “FF3F”,data area blank is “FF00”.If it’s encrypted,it will always be “0000” after
reading.The set point of the configuration is usually saved between program area and data area,is
only a few bytes,can click “Configuration Word” button to enter the setting interface and set the
configuration word of PIC series MCU,then write the chip.
 As for the configuration word of chip,the general user can read directly without too much
attention,it’s OK to write another chip directly when there is no the hint of encryption,the chip
encrypted also can be erased directly and written,just can not be read directly by programmer.If
use the program or data supplied from manufacturer we need to according to some document
description or check the MCU’s data of corresponding type and set the configuration word.
 When the RT809F is reading and writing PIC series,there will be a page of “FF FF”invalid region
in the buffer,which is for the two-way compatibility of the Xeltek 280U/580U/3000U
reading&writing program,data and configuration word with large consumption.
