This register contains the second choice of the first byte address of received frame. For LAPD frame,
SA27
SA22 is the SAPI value, SA21 is C/R bit and SA20 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.
