Status Bytes. In transitional timing mode, the status bytes indicate
whether a given row in the data contains acquisition information or
transition count information.

Pod 5
Pod 4 Pod 3
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
appropiate pod's Information bytes represent acquisition data. When that
bit is clear, the next bit shows if the Information bytes represent the first
word of a count. Together there are three possible combinations:
10 - This pods Information bytes contain acquisition data as obtained from
the target system.
01 - This pod's Information bytes contain the first word of a count.
00 - This pod's Information bytes contain part of a count other than the
first word.
