Note: After blowing, the programming is not reversible, even
after cycling the supply power. Although a register bit field fuse
cannot be reset after it is blown, additional bits within the same
register can be blown at any time until the device is locked. For
example, if bit 1 (binary 10) has been blown, it is still possible to
blow bit 0. The end result would be binary 11 (decimal code 3).
Locking the Device
After the desired code for each parameter is programmed, the
device can be locked to prevent further programming of any
parameters. See the Lock Mode section for lock pulse sequence.

Additional Guidelines
The additional guidelines in this section should be followed to
ensure the proper behavior of these devices:
• A 0.1 μF blowing capacitor, C
• The C
• The following programming order is recommended:
the VOUT pin and the GND pin during programming, to ensure
enough current is available to blow fuses.
application with a suitable C
is 10 nF for proper operation.) The power supply used for
programming must be capable of delivering at least 26 V and
300 mA. Be careful to observe the t
powering down the device after blowing each bit.
