A processing system includes configuration registers and a non-volatile memory with memory slots storing configuration data bits and error detection bits. A hardware configuration circuit sequentially reads the data bits from the non-volatile memory for storage in respective configuration registers by: receiving bits from a current memory slot; selectively asserting an error signal in response to comparison of received error detection bits with calculated error detection bits; storing the received bits to temporary registers where the error signal deasserted and other otherwise asserting a further error signal where the error signal is asserted. Otherwise, predetermined configuration data is stored to the temporary registers. The content of the temporary registers is then sequentially stored to the configuration registers. A reset signal is generated in response to the further error signal to reset the configuration registers.
