Crack Chip PIC18F8493 Flash

An A/D conversion can be started by the Special Event Trigger of the ECCP2 module. This requires that the CCP2M3:CCP2M0 bits (CCP2CON<3:0>) be programmed as ‘1011’ and that the A/D module is enabled (ADON bit is set).

When the trigger occurs, the GO/DONE bit will be set, starting the A/D acquisition and conversion, and the Timer1 (or Timer3) counter will be reset to zero. Timer1 (or Timer3) is reset to automatically repeat the A/D acquisition period with minimal software overhead (moving ADRESH:ADRESL to the desired location) to extract IC firmware.

The appropriate analog input channel must be selected and the minimum acquisition period is either timed by the user, or an appropriate TACQ time selected before the Special Event Trigger sets the GO/DONE bit (starts a conversion).

If the A/D module is not enabled (ADON is cleared), the Special Event Trigger will be ignored by the A/D module but will still reset the Timer1 (or Timer3) counter. This appendix discusses the considerations for converting from previous versions of a device to the ones listed in this data sheet.

Typically, these changes are due to the differences in the process technology used. An example of this type of conversion is from a PIC18F8493. This section discusses how to migrate from a Baseline device (i.e., PIC16C5X) to an Enhanced MCU device (i.e., PIC18FXXX).

The following are the list of modifications over the PIC18F8493 microcontroller family: A detailed discussion of the differences between the mid-range MCU devices (i.e., PIC18F8493) and the enhanced devices (i.e., PIC18FXXX) is provided in AN716, “Migrating Designs from PPIC18F8493”. The changes discussed, while device- specific, are generally applicable to all mid-range to enhanced device migrations.

This Application Note is available as Literature Number DS00716. A detailed discussion of the migration pathway and differences between the high-end MCU devices (i.e., PIC17CXXX) and the enhanced devices (i.e., PIC18FXXX) is provided in AN726, “PIC17CXXX to PIC18CXXX Migration”.
