Figure 8. Set Configuration Register (Software Method)

Note: 1. Only the Bus Configuration Register (BCR) and the Refresh Configuration Register (RCR) can be modified.

2. To program the BCR or the RCR on last bus write cycle, DQ0-DQ15 must be set to ‘0001h’ and ‘000h’ respectively.

3. The highest order address location is not modified during this operation.

4. The third write operation must be controlled by the Chip Enable signal.

Figure 9. Read Configuration Register (Software Method)

Note: 1. To read the BCR, RCR on last bus read cycle, DQ0-DQ15 must be set to ‘0001h’, ‘000h’ respectively.

2. The highest order address location is not modified during this operation.

3. The Chip Enable signal, E, must be held High for 150ns before reading the content of the Configuration Register.

4. The third write operation must be controlled by the Chip Enable signal.
