!Note for use
1) WAVE1, WAVE2, WAVE3 register, ATT123 register (at melody output), ATT register, ENVON register are changed
when output is a zero cross.
2) FREQ [5:0] register is changed instantaneously.
3) In the case that unsound part is set up WAVE 1,2,3 register, wave is stopped with a zero cross.
when it changes FREQ[5:0] before becoming off with a zero cross, new frequency wave output one cycle.
After wait for to do off with a zero cross, change FREQ[5:0].
4) 3 sound resources can only the setting of all sine wave or all special square wave.
5) 3 sound resources can only the setting of all DTMF/TONE or all MELODY.
6) A data value of registration etc. is held at the time of SLEEP.
7) At the time of RESET, a data value of registration etc. becomes initial value.
8) Maximum output level (ATT=0dB) of one sound resource is 342.5mVrms (typ).
Set up each ATT123 sol that output levels of totals 3 sound resources does not exceed,
because a maximum output level of DAC is 2.00V
PP
(707.1mVrms).
9) TNSEL of address 0 D4 is a setting register about whether output which of DTMF or MELODY.
10) FSEL of address 0 D3 is a setting register about whether make the setting of FREQ etc.
which of DTMF or MELODY.
