Claim 11:
12. A method comprising:
receiving, by a Master Out Slave In (MOSI) channel of a serial peripheral interface (SPI) of a subcontroller, a write address within an integrated circuit of the subcontroller to be written to;
receiving, by the MOSI channel, payload data to be written;
receiving, by the MOSI channel, a forward error-checking code usable to identify data corruption within the write address or the payload data;
calculating, by the integrated circuit, a reverse error-checking code based on the received write address and payload data, wherein the reverse error-checking code is usable to identify data corruption within the write address or the payload data;
providing, to a Master In Slave Out (MISO) channel of the SPI by the integrated circuit, the calculated reverse error-checking code;
comparing, by the integrated circuit, the forward error-checking code to the reverse error-checking code; and
writing, to the write address by the integrated circuit when the forward error-checking code matches the reverse error-checking code, the payload data.
