Manual Report Mode
In Manual Report Mode, the internal Error Counter starts to count the
received errors when the CNT_MD bit (MAINT6, 10H...) is set to ‘0’. When
there is a ‘0’ to ‘1’ transition on the CNT_TRF bit (MAINT6, 10H...), the data
in the counter will be transferred to (CNT0, 18H...) and (CNT1, 19H...), then
the counter will be reset. The errors occurred during the transfer will be
accumulated to the next round. If the counter overflows, a counter overflow
interrupt indicated by CNT_OV_IS bit (INTS1, 17H...) will be generated if
it is not masked by CNT_IM bit (INTM1, 12H...).
Figure-18 Manual Report Mode
Note: 1. It is recommended that users should do the followings within next round
of error counting: Read the data in CNT0 and CNT1; Reset CNT_TRF
bit for the next ‘0’ to ‘1’ transition on this bit.
3.8.3
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, 10H...) 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, 10H...) will generate
a logic error during the PRBS/QRSS transmission.
3.9
LINE DRIVER FAILURE MONITORING
The transmit driver failure monitor can be enabled or disabled by setting
DFM_OFF bit (TCF1, 03H...). If the transmit driver failure monitor is
enabled, the transmit driver failure will be captured by DF_S bit (STAT0,
14H...). The transition of the DF_S bit is reflected by DF_IS bit (INTS0,
16H...), and, if enabled by DF_IM bit (INTM0, 11H...), 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.
