first driven low. The bits of the instruction byte and address bytes are then shifted in, on
Serial Data input (D). Address bit A10 must be 0, address bits [A15:A11] and [A9:A7] are
Don't Care, and the data byte pointed to by [A6:A0] is shifted out on Serial Data output (Q).
If Chip Select (S) continues to be driven low, the internal address register is automatically
incremented, and the byte of data at the new address is shifted out. When the highest
address is reached, the address counter rolls over to zero, allowing the read cycle to
continue indefinitely.
The read cycle is terminated by driving Chip Select (S) high. The rising edge of the Chip
Select (S) signal can occur at any time during the cycle. The first byte addressed can be any
byte within any page.
The instruction is not accepted, and is not executed, if a write cycle is currently in progress.
