the device will return to the idle state once the CS pin has been deasserted. The WEL bit in the Status Register will be
reset back to the logical “0” state if the program cycle aborts due to an incomplete address being sent, an incomplete
byte of data being sent, the CS pin being deasserted on uneven byte boundaries, or because the memory location to be
programmed is protected or locked down.
While the device is programming, the Status Register can be read and will indicate that the device is busy. For faster
throughput, it is recommended that the Status Register be polled rather than waiting the t
data bytes have finished programming. At some point before the program cycle completes, the WEL bit in the Status
Register will be reset back to the logical “0” state.
The device also incorporates an intelligent programming algorithm that can detect when a byte location fails to program
properly. If a programming error arises, it will be indicated by the EPE bit in the Status Register.

Dual-Input Byte/Page Program
The Dual-Input Byte/Page Program command is similar to the standard Byte/Page Program command and can be used to
program anywhere from a single byte of data up to 256-bytes of data into previously erased memory locations. Unlike the
standard Byte/Page Program command, however, the Dual-Input Byte/Page Program command allows two bits of data to
be clocked into the device on every clock cycle rather than just one.
Before the Dual-Input Byte/Page Program command can be started, the Write Enable command must have been
previously issued to the device (see
