•  Bit 0: This bit indicates whether to use byte ‘0’ or page ‘1’ programming.  
•  Bit 1-3 are the pagesize bits, pagesize are given in bytes not words, see table

•  Bit 4-5 are not in use.  
•  Bit 6 must be set to ‘1’ when it is the very last page to be programmed, otherwise 

‘0’ 

•  Bit 7 indicates if a page write should be issued (Transfer data to flash). Normally it 

should always be set ‘1’. However, if the page size of the target device is too large 
to be covered by one Program Flash command (because the amount of available 
SRAM in STK500 is limited) this can be used to let 2 or more commands fill the 
page buffer of the target device. The transfer data to flash flag should then only be 
set on the last command. 

Note: 

Only Bit 0-3 are set in the XML file, cause Bit 6-7 are not static and must be 
controlled by the PC Frontend. 

This command will read data from the FLASH memory of the target device if it 
succeeds. For devices with the FLASH organized in pages, the data address and size 
used with this command must confirm to that of the device. I.e. one ReadFlash 
command is used to read one page in the target device.
