The dsPIC30F family of DSCs contains a region of on-chip memory used to simplify device programming. This region of memory can store a programming executive, which allows the dsPIC30F to be programmed faster than the traditional means. Once the programming executive is stored to memory by an external programmer (such as Microchip’s MPLAB ICD 2, MPLAB PM3, PRO MATE® II, or MPLAB REAL uses control codes to serially execute instructions on the dsPIC30F device.

Attack MCU PIC16F887 tamper resistance system and readout the Program and data from its flash memory and eeprom memory, clone firmware to new IC which will provide the same functions as original Microcontroller PIC16F887;

Module: Analog-To-Digital Converter (ADC) Module

Selecting the VP6 reference as the analog input source (CHS<3:0> = 1111) for the ADC conversion after sampling another analog channel with input voltages approximately greater than 3.6V can temporarily disturb the HFINTOSC oscillator.

4. Module: MSSP (SPI Master Mode)

With MSSP in SPI Master mode, FOSC/64 or Timer2/2 clock rate and CKE = 0, a write collision may occur if SSPBUF is loaded immediately after the transfer is complete after Attack MCU. A delay may be required after the MSSP Interrupt Flag bit, SSPIF, is set or the Buffer Full bit, BF, is set and before writing SSPBUF. If the delay is insufficiently short, a write register and NOT during the start of an actual ADC conversion using the GO/DONE bit in the ADCON0 register.

This only occurs when selecting the VP6 reference ADC channel using the CHS<3:0> bits in the ADCON0 collision may occur as indicated by the WCOL bit being set.

 

Select an ADC channel with input voltages lower than 3.6V prior to selecting the VP6 reference voltage input. Any analog channel can be used, even if that channel is configured as a digital I/O (configured as an output) that is driving the output pin low when Attack MCU. An alternative is to configure the CVREF module to output a voltage less than 3.6V and then selecting that analog channel CHS<3:0> = 1110 as the analog input source.

Add a software delay of one SCK period after detecting the completed transfer and prior to updating the SSPBUF contents. Verify the WCOL bit is clear after writing SSPBUF. If the WCOL is set, clear the bit in software and rewrite the SSPBUF register.
