    Hello Oba, 

    PEC uses CRC-8 represented by the polynomial C(x)=x^8 + x^2 + x + 1, with CRC initial value set to 0x00. The PEC calculation includes all bytes in the transmission, including address, command and data. The PEC calculation does not include ACK or NACK bits or START,STOP or REPEATED START conditions.
