Description
Reserved
These bits are reserved and should be written as 0 by user code
Port 0.4 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P0.4 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to P0.4 as an output.
Port 0.3 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P0.3 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to P0.3 as an output.
Port 0.2 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P0.2 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to P0.2 as an output.
Port 0.1 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P0.1 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to P0.1 as an output.
Port 0.0 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P0.0 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to P0.0 as an output.
Reserved
These bits are reserved and should be written as 0 by user code
GPIO11 Function Select Bit
This bit is cleared to 0 by user code to internally disable the LIN input data path. In this configuration GPIO11 is used to
support diagnostic read-back on all external high-voltage I/O pins (see HVCFG1[2:0])
This bit is set to 1 by user code to route input data from the LIN interface to both the LIN hardware
timing/synchronization logic and to the UART RxD (receive data). This mode must be configured by user code when
using LIN .
Reserved
These bits are reserved and should be written as 0 by user code
GPIO8 Function Select Bit
This bit is cleared by user code to 0 to configure the GPIO8 pin as a General Purpose I/O (GPIO) pin
This bit is set by user code to 1 to route the LIN input data to the GPIO8 pin. This mode can be used to drive the LIN
transceiver interface as a standalone component without any interaction from MCU or UART.
Reserved
These bits are reserved and should be written as 0 by user code
GPIO7 Function Select Bi
This bit is cleared by user code to 0 to configure the GPIO7 pin as a General Purpose I/O (GPIO) pin
This bit is set by user code to 1 to route data driven into the GPIO7 pin through the on-chip LIN transceiver to be output
at the LIN pin. This mode can be used to drive the LIN transceiver interface as a standalone component without any
interaction from MCU or UART.

Read/Write
This 32-bit MMR configures the direction of the GPIO pins assigned to Port0 (see Table 48). This register also sets
the output value for GPIO pins configured as outputs and reads the status of GPIO pins configured as inputs.
