Attacking Microchip MCU PIC18F66K22 Secured Memory can help to unlock the embedded firmware from microcontroller pic18f66k22, extract IC code in the format of heximal out from memory;
Multi-Master mode support is achieved by bus arbitration. When the master outputs address/data bits onto the SDAx pin, arbitration takes place when the master outputs a ‘1’ on SDAx, by letting SDAx float high and another master asserts a ‘0’. When the SCLx pin floats high, data should be stable. If the expected data on SDAx is a ‘1’ and the data sampled on the SDAx pin is ‘0’, then a bus collision has taken place. The master
sistema de resistencia a manipulaciones Microchip MCU PIC18F66K22 protegido contra ataques y firmware integrado de memoria cifrada de lectura que incluye programa binario de la memoria flash y datos heximales de la memoria eeprom, el código fuente original que contiene el microcontrolador bloqueado PIC18F66K22 se restaurará y copiará el software al nuevo microprocesador PIC18F66K22;
will set the Bus Collision Interrupt Flag, BCLxIF, and reset the I2C port to its Idle state (Figure 15-31).
If a transmit was in progress when the bus collision occurred, the transmission is halted, the BF flag is cleared, the SDAx and SCLx lines are deasserted and the SSPxBUF can be written to attacking microchip pic18f26k80 protection. When the user services the bus collision Interrupt Service Routine and

if the I2C bus is free, the user can resume communication by asserting a Start condition.
If a Start, Repeated Start, Stop or Acknowledge condition was in progress when the bus collision occurred, the condition is aborted, the SDAx and SCLx lines are deasserted and the respective control bits in the SSPxCON2 register are cleared. When the user services the bus collision Interrupt Service Routine and if the I2C bus is free, the user can resume communication by asserting a Start condition.
