Manufacturer:TI Description:MAIN MEMORY PAGE READ: A Main Memory Page Read allows the user to read data directly from any one of the 4096 pages in the main memory, bypassing both of the data buffers and leaving the contents of the buffers unchanged. To start a page read, an opcode of 52H or D2H must be clocked into the device followed by 24 address bits and 32 dont care bits. The first three bits of the 24-bit address sequence are reserved bits, the next 12 address bits (PA11 - PA0) specify the page address, and the next nine address bits (BA8 - BA0) specify the starting byte address within the page. The 32 dont care bits which follow the 24 address bits are sent to initialize the read operation. Fol- lowing the 32 dont care bits, additional pulses on SCK result in serial data being output on the SO (serial output) pin. The CS pin must remain low during the loading of the opcode, the address bits, the dont care bits, and the reading of data. When the end of a page in main memory is reached during a Main Memory Page Read, the device will con- tinue reading at the beginning of the same page. A low-to-high transition on the CS pin will terminate the read operation and tri-state the SO pin. |
