AT89C5131
Several Application Program Interface (API) calls are available for use by an application
program to permit selective erasing and programming of Flash pages. All calls are made
by functions.
All these APIs are described in detail in the following document on the Atmel web site.
The EXTRA ROW (XROW) includes 128 bytes. Some of these bytes are used for spe-
cific purpose in conjonction with the bootloader.
Table 43. XROW Mapping
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.
