<p>The present invention discloses a circuit, a user equipment, and a method for multiplexing multiple channels of voices. The circuit includes: an MCU, where the MCU includes at least two GPIO interfaces; and at least two SLICs, where each of the at least two SLICs includes an enabling CS port; the CS port of each of the at least two SLICs is separately connected to the at least two GPIO interfaces, and the at least two GPIO interfaces generate an enabling signal, and enable the at least two SLICs in a time division manner through the CS port of each of the at least two SLICs. The user equipment in the embodiments of the present invention includes the circuit, and the method provided by the embodiments of the present invention is applied to the circuit. By applying the technical solutions provided by the embodiments of the present invention, more SLICs may be added in a case in which resources of an SPI controller on the MCU are limited, thereby implementing multiplexing of multiple channels of voice signals.</p> |
