The status register indicates programming status:
While programming, the only valid commands are:
Suspending and Resuming Program (B0h/D0h)
The Program Suspend command halts an in-progress program operation, so that data can be read
from other locations of memory.

A Read Array command can be written to the CUI to read data from any block other than the
suspended block. The only other valid commands, while program is suspended, are:
WHRH1
1. When programming is complete, check the program status bits.
2. Clear the status register before attempting the next operation.
3. To prevent inadvertent status register reads, reset the CUI to read array mode.
1. After the programming process starts, write the Program Suspend command to the CUI.
2. Poll status register bits SR.7 and SR.2 to determine when the program operation has been
