ASAHI KASEI
When the STR bit is “1”, the transition among MONO, Stereo and SAP is operated using soft muting function. When the
STR bit is “0”, the transition among MONO, Stereo and SAP is operated immediately.
Notes:
MS0547-E-01
(1) Transition time. 768 LRCK cycles (768/fs) for both muting and unmuting.
(2) When the STR bit = “0”, a noise may occur at transition.
