8.1.2
(MODE.MDS(2:0) = 101; MODE2.MDS2(2:0)=101; MODE3.MDS3(2:0)=101)
Characteristics: address recognition, flag- and CRC generation/check, bit stuffing
Only the high byte of a 2-byte address field is compared to registers RAH(2:1). The
whole frame excluding the first address byte is stored in RFIFO (RFIFO2, RFIFO3).
8.1.3
(MODE.MDS(2:0) = 100; MODE2.MDS2(2:0)=100; MODE3.MDS3(2:0)=100)
Characteristics: flag- and CRC generation/check, bit stuffing
No address recognition is performed and each frame is stored in the RFIFO (RFIFO2,
RFIFO3).
8.1.4
SS7 protocol is supported for channel 1 only by means of several hardware features as
described in
