propose:
- if it's not too hard,    "forget" on every enable (or disable) (fallback: beginstep/ends\
tep)
  o doesn't handle the integ-det-pause cause, but that's hard and
    we will make that clear to the scientists (eventual    solution may    be 1MHz    encoder)
- turns out ric already does this

MHz Encoder Discussion

(with larry on oct 17, 23)

P,Q are limits

E error

A,B is for calculating position

Z is home

some get latched, there is a latch-clear

position is a signed integer

for errors have signal, counter and latch (only error is an error in encoding, likely because going too fast)

slaclab/high-rate-encoder-dev (devGui is there)

should we autohome (i.e. have firmware do it when it sees Z) or have scientists home it with software e.g. when absolute encoder is in the right place?  maybe doesn't matter?

counter range is ~100 million.
