Wired Remote Controller

_______________________________________________________________________________________

Note 1: Recommended properties of external switch for proper detection of 30 keys or key combinations.

Note 2: See the

Jack Insertion/Removal Detection section.

Note 3: Cb is the bus capacitance in pF.

Note 4: Key current depends on external key resistors and is calculated by VDD / (30.1kΩ + RSW).
