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.
