The flow described below shows how to program data in the Flash memory or in the EEPROM
data memory.
The bootloader programs on a page of 128 bytes basis when it is possible.
The host must take care that:
•
The boot loader answers with:
•
•
•
The data to program transmitted within a frame are in the same page.
‘.’ & ‘CR’ & ’LF’ when the data are programmed
‘X’ & ‘CR’ & ‘LF’ if the checksum is wrong
‘P’ & ‘CR’ & ‘LF’ if the Security is set
