The 32-bit MMR selects the pin function for each port pin.
Description
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_5 function select bit.
This bit is cleared by user code to 0 to configure the GPIO_5 pin as a general-purpose I/O (GPIO) pin.
This bit is set to 1 by user code to configure the GPIO_5 pin as LIN output for LIN conformance testing.
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_4 function select bit.
This bit is cleared by user code to 0 to configure the GPIO_4 pin as a general-purpose I/O (GPIO) pin.
This bit is set to 1 by user code to configure the GPIO_4 pin as LIN input for LIN conformance testing.
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_3 function select bit.
This bit is cleared by user code to 0 to configure the GPIO_3 pin as a general-purpose I/O (GPIO) pin.
This bit is set to 1 by user code to configure the GPIO_3 pin as MOSI, master output, and slave input data for the SPI port.
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_2 function select bit.
This bit is cleared to 0 by user code to configure the GPIO_2 pin as a general-purpose I/O (GPIO) pin.
This bit is set to 1 by user code to configure the GPIO_2 pin as MISO, master input, and slave output data for the SPI port.
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_1 function select bit.
This bit is cleared to 0 by user code to configure the GPIO_1 pin as a general-purpose I/O (GPIO) pin.
This bit is set to 1 by user code to configure the GPIO_1 pin as SCLK, serial clock I/O for the SPI port.
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_0 function select bit.
This bit is cleared to 0 by user code to configure the GPIO_0 pin as a general-purpose I/O (GPIO) pin.
This bit is set to 1 by user code to configure the GPIO_0 pin as SS, slave select input for the SPI port.
