A Result Value indicating the result of the
operation
Table 5-8. Valid Result Values for the answer to this command.
Value Description
STATUS_CMD_OK Operation succeeded
STATUS_RDY_BSY_TOUT
No response from target device within specified
timeframe
5.4 CMD_PROGRAM_FLASH_PP
This command will program data into 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 ProgramFlash
command is used to program one page in the target device.

Mode byte description
• 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
below.
• 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 STK600 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.
