The 32-bit MMR selects the pin function for each Port2 pin.
Description
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_6 Function Select Bit.
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_5 Function Select Bit.
Description
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_13 Function Select Bit.
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_12 Function Select Bit.
Reserved. These bits are reserved and should be written as 0 by user code.
GPIO_11 Function Select Bit.
Reserved. These bits are reserved and should be written as 0 by user code.
Set to 1 by user code to route the STI data output to the STI pin.
If this bit is cleared to 0 by user code, then the STI data is not to be routed to the external STI pin even if the STI
interface is enabled correctly.
Cleared by user code to 0 to configure the GPIO_6 pin as a general-purpose I/O (GPIO) pin.
Set to 1 by user code to configure the GPIO_6 pin as TxD, transmit data for UART serial port.
Cleared by user code to 0 to configure the GPIO_5 pin as a general-purpose I/O (GPIO) pin.
Set by user code to 1 to configure the GPIO_5 RxD, receive data for UART serial port.
Cleared to 0 by user code to route the LIN/BSD transmit data to an internal general-purpose I/O (GPIO_12) pad that
can then be written via the GP2DAT MMR. This configuration is used in BSD mode to allow user code to write output
data to the BSD interface, and it can also be used to support diagnostic write capability to the high voltage I/O pins
(see HVCFG1[2:0]).
Set to 1 by user code to route the UART TxD (transmit data) to the LIN/BSD data pin. This configuration is used in LIN mode.
Cleared to 0 by user code to internally disable the LIN/BSD input data path. In this configuration, GPIO_11 is used to
support diagnostic readback on all external high voltage I/O pins (see HVCFG1[2:0]).
Set to 1 by user code to route input data from the LIN/BSD interface to both the LIN/BSD hardware timing/synchronization
logic and to the UART RxD (receive data). This mode must be configured by user code when using LIN or BSD modes.
