6.1 Peripheral multiplexing description
Following we describe opportunity to use alternative interfaces using the properties of multiplexing pin.
Refer to the NXP's reference manual and documentation for further details.
6.1.1 SPI Interfaces
Using pin multiplexing 's features we may have the following SPI and IIS connections. The tables below show the output signals on the
Connector's module.
