Abstract
A method for verifying data in a memory device and a circuit. Data from a microcontroller unit or a data storage structure is copied to a register block. A checksum value and a checksum seed value are determined from the data copied to the register block. These values may be determined using a cyclic redundancy check technique. A verification value is determined using the checksum seed value and the checksum value, which verification value is used to verify the integrity of the data in the memory device. In accordance with another aspect the motor driver circuit includes a memory device configured to have a reserved data section, a non-reserved data section, and a checksum storage section. A register block is coupled to the memory device where the register block includes a checksum seed storage register; and a check function circuit is coupled to the storage register.
