Recover Microchip PIC18F2423 Memory Program

Recover Microchip PIC18F2423 memory program includes recover the content from both eeprom and flash, so it is necessary to get a better knowledge of the internal structure:

12-bit,up to 13-channel Analog-to-Digital
Converter module (A/D):
– Auto-acquisition capability
– Conversion available during Sleep
Dualanalog comparators with input multiplexing
High-currentsink/source 25 mA/25 mA
Threeprogrammable external interrupts
Fourinput change interrupts of IC recoverion
Upto 2 Capture/Compare/PWM (CCP) modules, one with Auto-Shutdown (28-pin devices)
EnhancedCapture/Compare/PWM (ECCP) module (40/44-pin devices only):
– One, two or four PWM outputs
– Selectable polarity
– Programmable dead time
– Auto-shutdown and auto-restart
