This application note describes a KEEL OQ code hop-
ping decoder implemented on a Microchip Mid-range
Enhanced FLASH MCU (PIC16F872). The software
has been designed as a group of independent modules
(standard C source files "C" ).
For clarity and ease of maintenance, each module cov-
ers a single function. Each module can be modified to
accommodate a different behavior, support a different
MCU, and/or a different set of peripherals (memories,
timers, etc.). M AN744
