| bool "Use two separate I2S ports for loopback" |
| help |
| Use separate I2S ports for transmit and receive. |

| config I2S_TEST_USE_I2S_DIR_BOTH |
| bool "Use I2S_DIR_BOTH value to perform RX/TX transfers" |
| default y if DT_HAS_NORDIC_NRF_I2S_ENABLED |
| help |
| Use the I2S_DIR_BOTH enumeration value to trigger commands in test |
| cases involving both reception and transmission. Use of this option |
| is essential for devices that cannot independently start and stop |
| the RX and TX streams. |
| |
| config I2S_TEST_USE_GPIO_LOOPBACK |
| bool "Use GPIO loopback" |
| default y if DT_HAS_NORDIC_NRF_I2S_ENABLED |
| help |
| Use wiring between the data-out and data-in pins for looping back |
| data. This option is intended to be used for devices that do not |
| provide the internal loopback functionality. |
| |
| config I2S_TEST_ALLOWED_DATA_OFFSET |
| int "Allowed offset in received data" |
| default 2 if DT_HAS_NORDIC_NRF_I2S_ENABLED |
| default 0 |
| help |
| Maximum allowed offset between sent and received samples. Non-zero |
| value of this option may be needed when GPIO loopback is used. |
