XROW Bytes
The EXTRA ROW (XROW) includes 128 bytes. Some of these bytes are used for spe-
cific purpose in conjonction with the bootloader.
Table 30. XROW Mapping
Hardware Conditions
It is possible to force the controller to execute the bootloader after a Reset with hard-
ware conditions.
During the first programming, the user can define a configuration on Port1 that will be
recognized by the chip as the hardware conditions during a Reset. If this condition is
met, the chip will start executing the bootloader at the end of the Reset.
See a detailed description in the applicable Document.
