The descriptions for the headphone insertion detection registers are shown in Table 21. The PCM5310 detects

the insertion status of a headphone plug using the GPIO pins through the register setting and writes the status to

the register, which can be read by the I2C interface. The status can also output to the GPIO pins, as shown in

Figure 41.
