The example in Table 19 shows the first super-frame with the settings NL = 3, MUX = 20 and p = 4 applied; the super-frame contains three frames. The
next super-frame will be a repeat of the first super-frame if bit FI is set to logic 0 (no super-frame inversion), or will start with the first frame having the
opposite sign if bit FI is at logic 1 (super-frame inversion) and the N-line inversion counter will also restart.
Super-frame inversion requires that the state of the previous super-frame is remembered, i.e., if the previous super-frame started ‘+’, then the next
super-frame must start ‘ ’. This has priority over inversions triggered by the counter, so that if the counter triggers an inversion at a super-frame
boundary and super-frame inversion is active, then the two do not cancel each other out but the super-frame inversion has priority.
