... right, was forgetting about case. But if you're trying to account for mixed case, I don't think the CR resolves it anyways: ASCII A = 0x41 --> 2 bits on ASCII T = 0x54 --> 3 bits on ASCII a = 0x61 --> 3 bits on ASCII t = 0x74 --> 4 bits on ASCII CR = 0x0D --> 3 bits on In sequence "Ta<CR>", all characters have an odd number of bits on and would produce the same parity value, and collectively would be indistinguishable from a corresponding constant M or S parity.
