Control data is communicated utilizing a multi-frame format that consists of individual frames each having a number of rows and columns. As each row is received from a transmitting unit, the data and position of the row within a frame is verified by use of a checksum and is immediately utilized by the receiving unit. This reduces the amount of storage that must be provided by the receiving unit for the reception of control information to that of a single row. In addition to verifying the row identification, the identity of each frame within the multi-frame is also verified before an individual row is utilized. In a first embodiment, the operation of generating the checksum is seeded with the current row number. In a second embodiment, the operation of generating the checksum is seeded with the result of an Exclusive OR operation of the current row number and frame number.
