The DCI standards provide tuned internal parallel split-termination resistors that are
always present (for receivers). The value of both the pull-up and pull-down resistors
mirror the resistance measured on the VRN/VRP pins, creating the Thevenin equivalent
resistance to the V
complementary single-ended drivers for outputs and differential receivers for inputs.

These standards are only available for bidirectional (input and output) signals. The T_DCI
standards provide tuned internal parallel split-termination resistors that are only present
when the 3-state control is enabled on the output buffer. The termination is disabled
whenever the output buffer is driving. The value of both the pull-up and pull-down
resistors mirror the resistance measured on the VRN/VRP pins, creating the Thevenin
equivalent resistance to the V
complementary single-ended drivers for outputs and differential receivers for inputs.

Table 1-36: Available I/O Bank Type
DCI provides tuned internal parallel split-termination resistors that are always present for
receivers. DCI versions are only available for unidirectional (input or output) signals. The
T_DCI versions limit the resistors to only be present when the 3-state control is enabled on
the output buffer (only when receiving). With T_DCI, the termination is disabled
whenever the output buffer is driving. The T_DCI versions are only available for
bidirectional signals (input and output). The value of both the pull-up and pull-down
resistors mirror the resistance measured on the VRN/VRP pins, creating the Thevenin
equivalent resistance to the V
complementary single-ended drivers for outputs, and differential receivers for inputs.
