Pin
The outputs will be on when the MUTE pin
is at the high level.
The outputs will be off when the MUTE pin
is at the low level ; in particular, the outputs
go to the high-impedance state at this
time.
When REG C (3.3VREG) is high, RESET
will be high.
When REG C (3.3VREG) is low, RESET
will be low.
Details of Operating voltage see section
Reset operation.
Reset output delay time setting.
The delay time until the point the reset
output switches from low to high is set by
the capacitor connected between this pin
and ground.
Reference to Reset operation.
