10.4.1.2 Data and EOT Block Definition
Data and EOT transfer blocks are used by the bootstrap loader to transfer data from the host to the
XRAM of the MCU. A data block contains a bulk of data, which has to be copied to the XRAM
beginning at an address which is defined by startaddress of a preceding header block. The number
of data bytes is also specified by the blocklength field of a proceeding header block.
The EOT block contains the last bytes of a data transmission to the XRAM. The number of the
remaining relevant bytes in the EOT block is given in no. of bytes.
Figure 10-11 shows the structure of Data and EOT block.
