The Read Status Register (RDSR) instruction is used to read the content of the Status

As shown in Figure 7, to send this instruction to the device, Chip Select (S) is first driven

low. The bits of the instruction byte are shifted in (MSB first) on Serial Data Input (D), the

Status Register content is then shifted out (MSB first) on Serial Data Output (Q).

If Chip Select (S) continues to be driven low, the Status Register content is continuously

shifted out.

The Status Register can always be read, even if a Write cycle (tW) is in progress. The Status
