SB, XM, SR and MP are 4 bits in the HST register. They can be set to 0 by
the specific instruction and tested.
SB is set to 1 by RegSR and RegSRB instruction, XM by RTNSXM
instruction and SR and MP should always be 0 (hardware related stuff).
HST=a sets all bits set to 1 in a to 0 in the HST register.
?HST=a test that all bits set to 1 in a are 0 in the HST register
