This register contains the first choice of the first byte address of received frame. For LAPD frame, SA17 - SA12 is the SAPI
value, SA11 is C/R bit and SA10 is zero.

This register masks (disables) the second byte address comparison of the incoming frame. If the mask bit is "1" the corresponding
bit comparisons with D_TEI1, D_TEI2 are disabled. Comparison with TEIG is always performed.
Note : For the LAPD frame, the least significant bit is the EA =1 bit.
