10.5. Application remarks

•

After loading a new program using by the boot loader, the BLJB bit must be set to allow user application to

start at RESET.

• A user bootloader can be mapped at address [SBV]00h. The byte SBV contains the high byte of the boot

address, and can be read and written by API.

• The API can be called during user application, without disabling interrupt.

The interrupts are disabled by some APIs, for complex operations.
