Active-high indicates that signaling bit updates are suspended for both
receive signaling buffer [RSIGn; addr 1A0–1BF] and stack [STACK; addr
0DA] register. SIGFRZ, clocked by RSB clock, goes high coinciding with
receive loss of frame alignment (see RLOF; addr 047) and returns low 6–9
ms after recovery of frame alignment.
