TMS320F28067: Errata SPRZ171 - Table 3-3

Hello team,

Hope you are doing well. When you get a chance please see below question from the customer:

We are using below part:

TMS   980

320F28067PZT

G4 A - 85AL18W

  G4

The Question I have is the A in the third line of markings indicating Rev A silicon?

The odd thing that confused me is the errata states Rev B silicon is the 1st TMS rev, but this part is marked TMS? 

I looked at table 3-3 from the errata, since we use TMS320F2808PZAR parts. The table implies it should be TMX.
