## QUP v3 mapping to protocols and GPIOs in QCS6490 and QCS5430

QCS6490 and QCS5430 contain 21 QUP v3 serial engines. Of these, 16 QUP v3 serial engines are allocated for the application processor and 5 QUP v3 serial engines are allocated for the sensor low-power island (SLPI) on the application digital signal processor (aDSP).

Select only one protocol in a QUP v3 serial engine at a time. For example, simultaneous UART and I2C functions aren't supported. Each QUP v3 serial engine has up to seven lanes (I/O), which are numbered from 0 to 6.

**Note** The top-level QUP v3 serial engines are used as the application processor and boot image. The low-power island (LPI) QUP v3 serial engines are used for the sensor subsystem and Qualcomm® Trusted Execution Environment (TEE) use cases.

The following table lists the default QUP v3 mapping to protocols and GPIOs.
