Figure 6. Memory Map When Program is Executing from Flash Memory
Internalself-testroutines

Following any reset, execution begins in the utility ROM.
The ROM software determines whether the program
execution should immediately jump to location 0000h,
the start of application code, or to one of the special
routines mentioned. Routines within the utility ROM are
firmware-accessible and can be called as subroutines by
the application software. More information on the utility
ROM contents is contained in the DS4830 User’s Guide.
Password
Some applications require protection against unau-
thorized viewing of program code memory. For these
applications, access to in-system programming, in-appli-
cation programming, or in-circuit debugging functions
is prohibited until a password has been supplied. The
password is defined as the 16 words of physical program
memory at addresses 0010h–001Fh.
A single password lock (PWL) bit is implemented in
the device. When the PWL is set to 1 (power-on-reset
default) and the contents of the memory at addresses
0010h–001Fh are any value other than all FFh or 00h, the
password is required to access the utility ROM, includ-
ing in-circuit debug and in-system programming routines
that allow reading or writing of internal memory. When
PWL is cleared to 0, these utilities are fully accessible
without the password. The password is automatically set
to all ones following a mass erase.
Detailed information regarding the password can be
found in the DS4830 User’s Guide.
