Name Required Description

dynamicterminationcontrol[] No

Input signal for bidirectional I/Os. Input port

[NUMBER_OF_CHANNELS - 1..0] wide. When

specified, this port selects from the core either Rs

code, when the input value is LOW; or Rt code, when

the input value is HIGH. Enable Rt only when the

bidirectional I/O is receiving input. When the

bidirectional I/O is not receiving input, disable this

port for optimal output performance and power

dissipation.

dynamicterminationcontrol_b No

Input signal for bidirectional I/Os. Input port

[NUMBER_OF_CHANNELS - 1..0] wide. When

specified, this port selects from the core either Rs

code, when the input value is LOW; or Rt code, when

the input value is HIGH. Enable Rt only when the

bidirectional I/O is receiving input. When the

bidirectional I/O is not receiving input, disable this

port for optimal output performance and power

dissipation. Port is available only when the USE_

DIFFERENTIAL_MODE parameter value is TRUE.

seriesterminationcontrol[] No Receives the current state of the pull up and pull

down Rs control buses from a termination logic

block. [WIDTH_STC * NUMBER_OF_CHANNELS -

1..0] wide. Port is applicable only when the USE_

TERMINATION_CONTROL parameter value is TRUE.

seriesterminationcontrol_b No Receives the current state of the pull up and pull

down Rs control buses from a termination logic

block. [WIDTH_STC * NUMBER_OF_CHANNELS -

1..0] wide. Port is applicable only when the USE_

TERMINATION_CONTROL parameter value is TRUE.

parallelterminationcontrol[] No Receives the current state of the pull up and pull

down Rt control buses from a termination logic

block. Input port [((WIDTH_PTC * NUMBER_OF_

CHANNELS) - 1)..0] wide. Port is applicable only

when the USE_TERMINATION_CONTROL parameter

value is TRUE.
