95 / 156 page  DS1155F1 95 CS43131 5.13 Example Sequences 5.13.12 DoP and PCM Mixing Ex. 5-18 shows steps necessary to mix DoP and PCM. The XSP is in clock master receiving DoP data with LRCLK at 176.4 kHz and SCLK at 8.4672 MHz. The ASP is clock master receiving PCM data with LRCLK at 44.1 kHz and SCLK at 2.8224 MHz. 5 Enable HP Detect HP Detect. 0xD0000 data (0xD0000) OR (0xC0) HPDETECT_CTRL HPDETECT_INV HPDETECT_RISE_DBC_TIME HPDETECT_FALL_DBC_TIME Reserved 11 x x x xx 0 Enable headphone detection 6 Wait for interrupt. Check if HPDETECT_PLUG_INT or HPDETECT_UNPLUG_INT is set in the Interrupt Status 1 register (0xF0000). Example 5-18.
