in order to return to normal unsecured operation. Power-on reset will also reset both.
The user is responsible for directing the device to invoke the flash programming subroutine to reprogram
the word $0000 into program memory location $00 1FF7. This is done by, for example, toggling a specific
pin, or by downloading a user-defined key through serial interfaces.
Note:
7.3 Product Analysis
The recommended method of unsecuring a secured device for product analysis of field failures is via the
method suggested in section 7.2.4. The customer would need to supply Technical Support with the details
of the protocol to access the subroutines in flash. An alternative method for performing analysis on a
secured device would be to mass-erase and reprogram the flash with the original code, but also either
modify the security word or else not program the security word.
Part 8 General Purpose Input/Output (GPIO)
8.1 Introduction
This section is intended to supplement the GPIO information found in the 56F801X Peripheral Reference
Manual and contains only chip-specific information. This information supercedes the generic information
in the 56F801X Peripheral Reference Manual.
8.2 Configuration
There are four GPIO ports defined on the 56F8014. The width of each port, the associated peripheral and
reset functions are shown in
