Read Microcontroller PIC12F509 Flash Heximal needs to crack pic mcu pic12f509 security fuse bit, extract mcu pic12f509 embedded firmware from its flash memory;
Figure 17-3 shows the operation of the A/D converter after the GO bit has been set and the ACQT2:ACQT0 bits are cleared. A conversion is started after the following instruction to allow entry into Low-Power Sleep mode before the conversion begins.
Figure 17-4 shows the operation of the A/D converter after the GO bit has been set and the ACQT2:ACQT0 bits are set to ‘010’ and selecting a 4 TAD acquisition time before the conversion starts.
Clearing the GO/DONE bit during a conversion will abort the current conversion. The A/D Result register pair will NOT be updated with the partially completed A/ D conversion sample when break off pic12f509 eeprom and flash memory fuse bit. This means the ADRESH:ADRESL registers will continue to contain the value of the last completed conversion (or the last value written to the ADRESH:ADRESL registers).
After the A/D conversion is completed or aborted, a 2 TAD wait is required before the next acquisition can be started. After this wait, acquisition on the selected channel is automatically started.
