Receive Data Flow
Note 1 Only if a 2-byte address field is defined (MDS0 = 1 in MODE register).
Note 2 Comparison with Group TEI (FF ) is only made if a 2-byte address field is defined
H
(MDS0 = 1 in MODE register).
Note 3 In the case of an extended, modulo 128 control field format (MCS = 1 in SAP2 register)
the control field is stored in the RHCR in compressed form (I frames).
Note 4 In the case of extended control field, only the first byte is stored in the RHCR, the
second in the RFIFO.
