Modifiable Primitives
As shown in Table 1-7 and Table 1-8, only certain attributes are modifiable for any
primitive. These attributes help to define the protocol used by the primitive. Only the
GT_CUSTOM primitive allows the user to modify all of the attributes to a protocol not
supported by another transceiver primitive. This allows for complete flexibility. The other
primitives allow modification of the analog attributes of the serial data lines and several
channel-bonding values.
