COL/LPBK
I
TBI Mode Loopback. In the TBI mode, COL
is used to indicate loopback on the TBI.
When a “0 - 1" transition is sampled on this
pin, bit 0.14 is set to 1.
When a “1 - 0" is sampled on this pin, bit
0.14 is reset to 0.
If this feature is not used, the COL pin
should be driven low on the board. This pin
should not be left floating in TBI mode.
