... The W25X10A/20A/40A/80A supports Dual output operation when using the “Fast Read with Dual Output” (3B hex) instruction. This feature allows data to be transferred from the Serial Flash memory at twice the rate possible with the standard SPI. This instruction is ideal for quickly downloading code from Flash to RAM upon power-up (code-shadowing) or for applications that cache code-segments to RAM for execution ...

... Status Register Protect (SRP) and Block Protect (TB, BP2, BP1, and BP0) bits. These Status Register bits allow a portion or all of the memory to be configured as read only. Used in conjunction with the Write Protect (/WP) pin, changes to the Status Register can be enabled or disabled under hardware control ...
Page 11
... CONTROL AND STATUS REGISTERS The Read Status Register instruction can be used to provide status on the availability of the Flash memory array, if the device is write enabled or disabled, and the state of write protection. The Write Status Register instruction can be used to configure the device write protection features. See Figure 3. ...

... Write, Program or Erase must complete on a byte boundary (CS driven high after a full 8-bits have been clocked) otherwise the instruction will be terminated. This feature further protects the device from inadvertent writes. Additionally, while the memory is being programmed or erased, or when the Status Register is being written, all instructions except for Read Status Register will be ignored until the program or erase cycle has completed ...

... The Write Status Register instruction allows the Block Protect bits (TB, BP2, BP1 and BP0 set for protecting all, a portion, or none of the memory from erase and program instructions. Protected areas become read-only (see Status Register Memory Protection table). The Write Status Register instruction also allows the Status Register Protect bit (SRP set ...

... DO pin at the falling edge of CLK with most significant bit (MSB) first. The address is automatically incremented to the next higher address after each byte of data is shifted out allowing for a continuous stream of data. This means that the entire memory can be accessed with a single instruction as long as the clock continues. The instruction is completed by driving /CS high. The Read Data instruction sequence is shown in figure 8 ...
