Copy PIC12F519 MCU Flash Memory Firmware needs to break microcontroller pic12f519 protective system, and readout source code from pic12f519t microprocessor flash memory;
The ADCON2 register allows the user to select an acquisition time that occurs each time the GO/DONE bit is set.
When the GO/DONE bit is set, sampling is stopped and a conversion begins. The user is responsible for ensuring the required acquisition time has passed between selecting the desired input channel and setting the GO/DONE bit.
This occurs when the ACQT2:ACQT0 bits (ADCON2<5:3>) remain in their Reset state (‘000’) and is compatible with devices that do not offer programmable acquisition times.
If desired, the ACQT bits can be set to select a programmable acquisition time for the A/D module to unlock microcontroller pic12f519 fuse bit. When the GO/DONE bit is set, the A/D module contin- ues to sample the input for the selected acquisition time, then automatically begins a conversion.
Since the acquisition time is programmed, there may be no need to wait for an acquisition time between selecting a channel and setting the GO/DONE bit. In either case, when the conversion is completed to unlock microprocessor pic12f519 security fuse bit, the GO/DONE bit is cleared, the ADIF flag is set and the A/ D begins sampling the currently selected channel again.
If an acquisition time is programmed, there is nothing to indicate if the acquisition time has ended or if the conversion has begun.
