Input status bitInside the SFR ( special function register ) related with RAM and BUS, why the input status bit in an interface circuit is cleared as soon as the Input data buffer is read?
For example: PC out, MAR in, read, clear Y (register), set carry in........ Why there clear Y so important? If every MDR out will Y in. |
