Hi Here is some info that I got from M2 team.
The chip itself look like old M2 1.33b Sx version
Changes are as follows -
B + I always connect
C,D,E -do not connect
H only connect for Jap
F + G - do not connect (these wires are not required under normal operation)
Reset - do not connect
3.3V (Power) connection is optional (Chip takes it's power from the bus and is quite fine with this).
Pictures will follow soon.
