... Mute Pulse Generation The CXA2513M has one voltage comparator built-in. The built-in voltage comparator is used to produce mute pulse during the depress of the preset mode switches. During depress the switch, there is a voltage pulse of about 1V depending appearing at the cathode of the LEDs. The mute detector comparator is used to detect this voltage changes at the cathode of LEDs and produce mute pulse at Pin 12. The polarity of the mute pulse can be set. When the M_DET+ pin (Pin 18) is higher than the M_DET– ...
