TERMINATION_CONTROL_BLOCK
Specifies the control block used for calibrated on-chip termination (OCT) and impedance matching for
an I/O pin. OCT helps to prevent signal reflections and maintain signal integrity. This option is ignored if
it is applied to anything other than an I/O pad, input buffer, or output buffer. This option should only be
used on I/O pins which have a calibrated termination assignment.
