ALC/DAC Control (64H)
DEM1-0: De-emphases response (Table 23)
Default: “01” (OFF)
TM1-0: Soft Mute Time Select (Table 27)
Default: “00” (1024/fs)
HPDT: Headphone Jack Insertion Detection Function Enable
0: OFF (default)
1: ON
ATSW: Headphone/Speaker Automatic Switch Function Enable by Headphone Jack Insertion (Table 35, Table 36)
0: OFF
1: ON (default)
ATPU: Headphone-Amp Automatic Power-up Function Enable by Pen Touch (Figure 38)
0: OFF (default)
1: ON
DATTC: DAC Digital Attenuator Control Mode Select
0: Independent
1: Dependent (default)
When DATTC= “1”, ATTL6-0 bits control both Lch and Rch at the same time. ATTR6-0 bits are not changed
when the ATTL6-0 bits are written.
REF5-0: Maximum IPGA value at ALC1 Recovery Operation (Table 21)
Default: “2DH” (+19dB)
During the ALC1 recovery operation, if the IPGA value exceeds the setting maximum value (REF5-0 bits) by
gain operation, then the IPGA does not become larger than the maximum value.
HPINT: INTN pin Output Enable for Headphone Jack Detection
Default: “0” (OFF)
When HPINT bit = “1”, INTN pin is enabled to output the interrupt signal of headphone jack detection.
■
ALC Control (66H)
LTM1-0: ALC1 limiter operation period at zero crossing disable (ZELMN bit = “1”) (Table 17)
Default: “00” (0.5/fs)
The IPGA value is changed immediately when zero crossing is disabled (ZELMN bit = “1”). When the IPGA
value is changed continuously, the change is done by the period specified by the LTM1-0 bits.
WTM1-0: ALC1 Recovery Waiting Period (Table 19)
Default: “00” (128/fs)
WTM1-0 bits set a period of recovery operation when any limiter operation does not occur during the ALC1
operation.
ZTM1-0: ALC1 zero crossing timeout selection (Table 18)
Default: “00” (128/fs)
When the IPGA performs zero crossing or timeout, the IPGA value is changed by the
μ
P WRITE operation,
ALC1 recovery operation or ALC1 limiter operation (ZELMN bit = “0”).
