MTA81010
14.0
CONFIGURATION FUSES
The configuration EPROM consists of four EPROM
fuses which are not part of the normal EPROM for
program storage.
Two are for the selection of the oscillator type, one is
the watchdog timer enable fuse, and one is the code
protection fuse.
OTP or QTP devices have the oscillator configuration
programmed by the factory and the parts are tested
accordingly. The packages are marked with the suffixes
XT, RC, HS or LP following the part number to identify
the oscillator type and operating range.
14.1
Customer ID Code
The MTA81010 series has 16 special EPROM bits
which are not part of the normal program memory.
These bits are available to the user to store an identifier
(ID) code, checksum, or other informative data. They
cannot be accessed during normal program execution.
Programmers designed for the MTA81010 provide
special commands to read or write these ID bits.
14.2
Code Protection
The program code written into the EPROM can be
protected by programming the code protection fuse
with "0".
When code protected, the contents of the program
EPROM cannot be read out in a way that the program
code can be reconstructed. In addition, all memory
locations starting at 040h and above are protected
against programming.
It is still possible to program locations 000h - 03Fh, the
ID locations and the configuration fuses.
Note that the configuration fuses and the ID bits can
still be read, even if the code protection logic is active.
14.2.1
VERIFYING A CODE-PROTECTED
PIC16C54
When code protected verifying any program memory
location will read a scrambled output which looks like
"00000000XXXX" (binary) where X is 1 or 0. To verify a
device after code protection, follow this procedure:
a)
First, program and verify a good device without
code protecting it.
b)
Next, blow its code protection fuse and then load
its contents in a file.
c)
Verify any code-protected PIC16C54 against
this file.
