2.13.1 Bitmapping for Binary Data to PAM Signals
This section describes how the binary data of the data source (e.g. a PRBS) is
mapped to the different levels of a PAM-4, PAM-5, PAM-8, PAM-10, PAM-12 or
PAM-16 signal.
Definition:
 A PAM-n signal has n levels.
 The level number 1 is associated with the low level.
 The level number n is associated with the high level.
