Items to be set by command are as follows: Continue with Google or Continue with Facebook. Prior to starting a data transmission or reception, the A must be loaded with a set of control words generated by the microprocessor. Memory Interfacing in Continue with Google Continue with Facebook.

To get absolute address, all remaining address lines A 1 —A 15 are used to decode the address for A. Therefore, prior to data transfer, a set of control words must be loaded into the mode instruction and control instruction registers interfacinng A.

If sync characters were written, a function will be set because the writing of sync characters constitutes part of. These control signals define the complete functional definition of the A and must immediately follow a reset operation internal or external.
