Clause 49.2.13.2.3 states that
T_BLOCK_TYPE will = C when:
a)..
b)'one valid ordered set and four valid control characters other than /O/, /S/ and /T/'
c)
Our silicon rev 2.0 behaves slightly differently:
T_BLOCK_TYPE will = C when:
a)
b)'one valid ordered set and four valid control characters other than /E/, /O/, /S/ and /T/'
c)..
The errata only mentions an example pattern that can be mis-classified.

In this example, bits 39:8 form a valid ordered set and bits 71:40 comprise of 4 control characters other than /O/,/S/,/T/ (satisfies the requirement for C type). However, this pattern is incorrectly encoded as "E" instead of "C".
