ADDITIONAL STATUS
The additional status contains 4 bytes of Status for the SRD991 .
These bytes may be reset via a reset status under the test menu . This action will also clear the More Status flag within the
Secondary Status and the SSTAT-Err flag within the Primary Status, if the Secondary Status is empty .
Byte 1 contains system errors. The individual bits of the status byte are defined below . When the specified condition exists,
the status bit will be set to One otherwise, the status bit will be Zero . Byte 3 contains the same information but historically -
that is the condition existed but has been cleared .
