D0: NONAUDIO
NONAUDIO=0: Interpolation is enabled
C2 flag from EST pin output at 16 bit audioword unit.
NONAUDIO=1: Interpolation is disabled, prohibit interpolation.
C2 flag from EST pin output at 8 bit data byte unit.
D1: ECCMOD (Error correction mode)
ECCMOD=0: C1:2 error correction,C2:4 errors correction
ECCMOD=1: C1:2 error correction,C2:2 errors correction
D2: FLPDIS (False lock protection circuit disable)
FLPDIS=0: False lock protection circuit on
FLPDIS=1: False lock protection circuit off
(Refer to address 07h)
D3: PFHEN (VCO oscillation frequency upper limiter enable)
PFHEN=0: VCO oscillation frequency limiter is stopped
PFHEN=1: VCO oscillation frequency limiter is active
Limiter value = 8.6436MHz X 1.3 X S (S:Playback speed)
D4: HFDDIS (HFD disable)
HFDDIS=0: HFD input enable
HFDDIS=1: HFD input disable
D5:GAINCNT(CLV gain control)
D6:GAINSEL(CLV gain select)
GAINCNT=0: Normal gain mode.
GAINCNT=1: CLV gain control mode.
CLV gain can be selected 1/2 and 1/4 of normal gain by GAINSEL register.
