The header field contains the firmware signature data (0x1122). This field is fixed by the PL360 embedded firmware and is used to check if this firmware runs properly.
Info: Due to the
16-bit configuration used in this SPI firmware transaction, the firmware signature is
stored in memory as 0x2211.
The payload field depends on the PLC communication stack in use (G3 or PRIME). For further information, refer to atpl360_comm.h file.
