Description
TBI Receive Data code group bit 9. In the
TBI mode, RX_ER is used as RXD9.
RXD[9:0] are synchronous to RCLK0 and
RCLK1.
TBI Valid Comma Detect. In the TBI mode,
CRS is used as COMMA.
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.
