ADOWN (Analog Down)... Analog power supplies can be removed from OPL3-SA3, if
ADOWN=“1”.
Set this bit to “0”, before analog power is supplied again.
PSV (power save)...
Setting this bit to “1” makes OPL3-SA3 in power save mode
that is categorized into two types.
Power save mode 1
where PSV=PDX=”1”, clock oscillation is disabled and power
dissipation of digital portion becomes about 100uA(typ.), and that of
analog portion becomes about 5mA(typ.).
Power save mode 2
where PSV=”1” and PDX=0, clock oscillation is active. However
power dissipation of digital portion becomes about 10mA(typ.), and
that of analog portion becomes about 5mA(typ.).
PDN (Power down)...
Setting this bit to “1” makes in power down mode.
PDX (Oscillation stop)...
Setting this bit to “1” makes the clock oscillation halt.
