13.12.1 HEADPHONE JACK DETECT
The IN2L and IN2R pins can be selected as headphone jack detect inputs, to enable automatic
control of the analogue outputs when a headphone is plugged into a jack socket.
Jack Detection on the IN2L or IN2R pins is enabled by register bits JDL_ENA or JDR_ENA
respectively. When Jack Detection is enabled, the associated second level interrupts
CODEC_JCK_DET_L_EINT and CODEC_JCK_DET_R_EINT indicate the status of the jack socket.
See Section 13.12.7 for further details.
The Headphone Jack Detect function requires the internal slow clock to be enabled - see
Section 12.3.6.
