The MicroVAX-II supports the *bit field instructions of the VAX*. This is
*not* the same as supporting "bit addressing". Does the MicroVAX-II have
the ability to do a "movl" to an arbitrary *bit* boundary in memory? A
"movc5" to an arbitrary *bit* boundary in memory? Unless it's got a whole
set of bit-boundary instructions (i.e., unless they've added a bit-boundary
version of most of the instructions it supports), it doesn't support "bit
addressing" in the general sense.
