1) CNTL-Z REGISTER
It is a register to control zero cross mute of audio data, phase terminal
control, phase servo control and having or not of CRCF in data SQDT.

DATA = 0
D3 Zero cross mute is OFF
D2 -
D1 The phase servo is acted by frame sync
D0 SQDT outputs except for SQOK
DATA = 1
Zero cross mute is ON
-
The phase servo is controlled by base
counter
SQDT=CRCF when S0S1='H'
