SYS
This is an information flag, independent of the BOOT_DONE_SYS. This bit is set
when the boot status XDATA variable bBoot_BootStat is not equal to 0x00, signal-
ling error during boot.
It is recommended that the user code reads this bit and possibly make decisions
whether to continue with the execution of the loaded RAM code, which might not be
complete, or signal to a user a problem, by, for example, blinking LED in some not-
ordinary fashion.
1 BOOT_ Boot routine finished flag.
DONE_ ^{Always set to 1 at the end of the boot.}
SYS
0 CODE_ Run User Code in RAM.
RUN_SYS Used for Factory and User program states, ignored in Run state. When this bit is set
the boot routine will jump to CODE address 0x0000. Forced by the debugging chain if
the device is connected to the IDE.
