LM FPGA code for 7101 with PPS functionality and EM3000 motion data only

rev 8488 - Dec 2009 Special Customer Release (only for small fpga)

Incorporate changes made by Zeuxion to improve error recovery

This is an upgrade of rev 8458 and does not have crc error fixes 

following are notes from rev 8458

This version is follow up of 8448 that based on version 8040. 

Note only bits[11:8] and [3:0] are different from 8040.

Trigger in is disabled and motion data is set to EM3000 with 9X status accepted

FPGA specicific notes relative to 8040

a) intodroduce extra bit eniopf (lmcfg[3]) to enable iop "functions" and disable debug functions and conversely
b) lmcfg[11:8], lmcfg[3:0] is visible in the revision register 9
c) allow an "iop" port in xarbnew.v
d) only files changed relative to 8040 are lmvx03.v and xarbnew.v
