Figure 6 shows the instruction sequence of the write disable operation.
Read Status Operation
The read status operation code is b'0000 0101 and it lists the MSB first. You can use
the read status operation to read the status register. Figure 7 and Figure 8 show the
status bits in the status register of the EPCS devices.
Setting the write in progress bit to 1 indicates that the EPCS device is busy with a
write or erase cycle. Resetting the write in progress bit to 0 indicates no write or erase
cycle is in progress.
