Write a parity checker routine that examines a byte in memory for correct parity. For even parity, the number of ones in a byte should be an even number. For odd parity, the number of ones should be an odd number. Create two small blocks of data, one assumed to have even parity and the other assumed to have odd parity. Introduce errors in both sets of data, writing the value 0xDEADDEAD into register r0 when an error occurs.
