Figure-18 Manual Report Mode
Note: It is recommended that users should do the followings within next round of error count-
ing: Read the data in CNT0 and CNT1; Reset CNT_TRF bit for the next ‘0’ to ‘1’ tran-
sition on this bit.
3.9.3
BIPOLAR VIOLATION AND PRBS ERROR INSERTION
Only when three consecutive ‘1’s are detected in the transmit data
stream, will a ‘0’ to ‘1’ transition on the BPV_INS bit (MAINT6, 12H...) gen-
erate a bipolar violation pulse, and the polarity of the second ‘1’ in the series
will be inverted.
A ‘0’ to ‘1’ transition on the EER_INS bit (MAINT6, 12H...) will generate
a logic error during the PRBS/QRSS transmission.
3.10 LINE DRIVER FAILURE MONITORING
The transmit driver failure monitor can be enabled or disabled by setting
DFM_OFF bit (TCF1, 05H...). If the transmit driver failure monitor is
enabled, the transmit driver failure will be captured by DF_S bit (STAT0,
16H...). The transition of the DF_S bit is reflected by DF_IS bit (INTS0,
18H...), and, if enabled by DF_IM bit (INTM0, 13H...), will generate an inter-
rupt. Whenthere is ashort circuit ontheTTIPn/TRINGn port, theoutput cur-
rent will be limited to 100 mA (typical), and an interrupt will be generated.
In hardware control mode, the transmit driver failure monitor is always
enabled.
