FUNCTIONAL DESCRIPTION
IDT82V2082
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.

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. When there is a short circuit on the TTIPn/TRINGn port, the output cur-
rent will be limited to 100 mA (typical), and an interrupt will be generated.
