Note that the initial pass through the Read Status flow chart will generate a 16-bit CRC value that is the  
result of clearing the CRC generator and then shifting in the command byte followed by the two address  
bytes, and finally the data bytes beginning at the first addressed memory location and continuing through  
to the last byte of the addressed EPROM Status data page. The last byte of a Status data page always has  
an ending address of xx7 or xxFH. Subsequent passes through the Read Status flow chart will generate a  
16-bit CRC that is the result of clearing the CRC generator and then shifting in the new data bytes starting  
at the first byte of the next page of the EPROM Status data field.  
This feature is provided since the EPROM Status information may change over time making it impossible  
to program the data once and include an accompanying CRC that will always be valid. Therefore, the  
Read Status command supplies a 16-bit CRC that is based on and always is consistent with the current  
data stored in the EPROM Status data field.
