Pod 3 Pod 2 Pod 1
Each pod uses two bits to show what is being represented in the
corresponding Information bytes. Bits 10,8,6,4 and 2 are set when the
appropriate pod’s Information bytes represent acquisition data. When
that bit is clear, the next bit shows if the Information bytes represent the
fust word of a count. Together there are three possible combinations:
10 - This pod’s Information bytes contain acquisition data as obtained from
the target system.
01 - This pod’s Information bytes contain the frost word of a count.
00 - This pod’s Information bytes contain part of a count other than the
first word.
