Continue with Google Continue with Facebook. These control signals define the complete functional definition of the A and must immediately follow a reset operation internal or external.

The format of status word is shown below.

Mode instruction format, Synchronous mode Command Instruction: Block Diagram of Programmable Interfcaing Contr To implement serial communication the CPU must inform the A all details such as mode, baud rate in case of asynchronous modestop bitsparity etc. The control words are split into two formats. Therefore, prior to data transfer, a set of control words must be loaded into the mode instruction and control instruction registers of A.
