The service status word is made up of 8 hexidecimal digits. To decode this word, convert
each digit int
o a 4-digit binary number in the same manner as the system status word,
which is described in Decoding system status words on page 102.
Each binary digit (bit) represents a ag that is either acve (state 1) or not acve (state
0). To help decode the service status word, each bit is numbered (starng with 0 for the
least signicant to 31 for the most signicant) as shown in Decoding system status words
on page 102. The meaning of each bit in the service status word is given in Flashing
service codes on page 100.

Cleared on full BRIM compleon, provided
no step forward, or these three condions:

or not BRIM underway.
3) TMP stop while BRIM underway.
