Not internally connected pins.
Open drain output of the tone decoder to the main
microcontroller for DiSEqC 2.0 data decoding. It is LOW
when tone is detected on DETIN pin.
External modulation logic input pin which activates the 22
kHz tone output on the V
Needed for internal pre-regulator filtering. The BYP pin is
intended only to connect an external ceramic capacitor. Any
connection of this pin to external current or voltage sources
may cause permanent damage to the device.
Two I²C bus addresses available by setting the Address pin
level voltage. See address pin characteristics
The resistor “RSEL” connected between ISEL and GND
defines the linear regulator current limit threshold by the
equation: Imax(typ.)=10000/ RSEL.
