FREQ [5:0] register changed instantaneously. case that unsound part WAVE 1,2,3 register, wave stopped with zero cross. when changes FREQ[5:0] before becoming with zero cross, frequency wave output cycle. After wait with zero cross, change FREQ[5:0]. sound resources only setting sine wave special square wave. sound resources only setting DTMF/TONE MELODY. data value registration etc. held time SLEEP. time RESET, data value registration etc. becomes initial value. Maximum output level (ATT=0dB) sound resource 342.5mVrms (typ). each ATT123 that output levels totals sound resources does exceed, because maximum output level 2.00VPP (707.1mVrms).
