The program status informs the operating status of auto write operation to the CPU. When a write
error occurs, it is set to 1.
The program status is reset to 0 when cleared.

When the program status or erase status = 1, the following commands entered by command write are
not accepted.
Also, in one of the following cases, both SR4 and SR5 are set to 1 (command sequence error):
