Detection
5.2. Audio Accessory Detection
Audio
accessories are detected when the ID_CON pin resistance to GND is approximately 1M. Configurations for this audio
accessory shown in Figure 12 and Figure 13 .

Audio Accessory with Full Wired Remote Control (1% Resistors)
The FSA9280A can detect and differentiate between regular
key presses, long key presses, and a stuck key. The
definition of the key press timing is user configurable by
writing the Timing Set 1 (08h) and Timing Set 2 (09h)
registers. Timing diagrams for the key press detection are
shown below in Figure 14 and Figure 15.
