SFSR(7:4) Reserved
SFSR(3) Status of loop back error check.
A “1” indicates a loop back error occurred, which will be entered for
interrupt arbitration.
It can be cleared by the processor by a write to this register with
D(3) equal to “1”.
SFSR(2:1)
Certification of returned data as Valid (This feature
implies the transmitted data is being returned by the remote
receiver. )
Sets automatic checking of returned data. This mode stores
transmitted data and compares it to data returned from the remote
receiver. It is used where relative short delay times are available, up
to two characters in time . This mode will totally relieve the
processor of this task where certainty of transmission and reception
is required. The transmitted data is looped back by the remote
station with a half–bit time delay. The local transmitted data is
internally sent to the local receiver for comparison. An interrupt is
generated in the case of an error (data mismatch, parity or framing).
00 = The checking is disabled
01 = Return data is clocked in on rise of TxC
10 = Return data is clocked on of rise of TxCN
00 = Reserved

Bypass divide by 16 counter in all TxC and RxC.
TRR [6:0] – Chip Revision Code
Indicates the revision of the chip. Initial code will be
