The external bus selection register (EBSR) controls all the pin multiplexing functions on the device. This section discusses how to program the external bus selection register (EBSR) to select the desired peripheral functions and pin muxing. See the individual pin mux sections for pin muxing details for a specific muxed pin. After changing any of the pin mux control registers, it will be necessary to reset the peripherals that are affected. The SPI, UART, I2S2, I2S3, and GPIO signal muxing is determined by the value of the PPMODE bit fields in the External Bus Selection Register (EBSR) register.
