Zarlink Semiconductor Inc.
Table 5 - Diagnostic Register
Note 1:
When bits 4-7 of the Diagnostic Register are all set to one, the DNIC operates in one of the default modes as defined in Table
4a, depending upon the status of bit-3.
Note 2:
Do not use L
OUT
to L
IN
loopback in DN/SLV mode.
Do not use DSTo to DSTi loopback in MOD/MAS mode.
Note 3:
The Diagnostics Register Reset bit (bit 2) of the Control Register determines the reset state of the Diagnostics
Register. If, on writing to the Control Register, this bit is set to logic “0”, the Diagnostics Register will be reset
coincident with the frame pulse. When this bit is logic “1”, the Diagnostics Register will not be reset. In order to use
the diagnostic features, the Diagnostics Register must be continuously written to. The output C-channel sends
status information from the Status Register to the system along with the received HK bit as shown in Table 6.
In MOD mode, the CD port is no longer an ST-BUS but is a serial bit stream operating at the bit rate selected. It
continues to transfer the C-channel but the D-channel and the HK bit no longer exist. DUAL port operation must be
used in MOD mode. The C-channel is clocked in and out of the CD port by TCK and CLD with TCK defining the bits
and CLD the channel boundaries of the data stream as shown in Figure 8.

Reg Sel-1
Register Select-1. Must be set to ’0’ to select the Diagnostic Register.

Reg Sel-2
Register Select-2. Must be set to ’1’ to select the Diagnostic Register.

All loopback testing functions disabled. Normal operation.
DSTi internally looped back into DSTo for system diagnostics.
L
OUT
is internally looped back into L

for system diagnostics.
2
DSTo is internally looped back into DSTi for end-to-end testing.

FUN
1
Force Unsync. When set to ’1’, the DNIC is forced out-of-sync to test the SYNC
recovery circuitry. When set to ’0’, the operation continues in synchronization.
5
PSWAP
1
Polynomial Swap. When set to ’1’, the scrambling and descrambling polynomials
are interchanged (use for MAS mode only). When set to ’0’, the polynomials retain
their normal designations.
6
DLO
1
Disable Line Out. When set to ’1’, the signal on L
OUT
is set to V
Bias
. When set to ’0’,
L
OUT
pin functions normally.
7
Not Used
Must be set to ’0’ for normal operation.
