Description
Reserved, this bit is reserved and should be written as 0 by user code
Port 2.6 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P2.6 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to P2.6 as an output.
Port 2.5 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P2.5 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to P2.5 as an output. This configuration is used to support
diagnostic write capability to the high-voltage I/O pins.
Port 2.4 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P2.4 as an input. This configuration is used to support
diagnostic read-back capability from the high-voltage I/O pins(see HVCFG1[2:0]).
This bit is set to 1 by user code to configure the GPIO pin assigned to P2.4 as an output.
Reserved
These bits are reserved and should be written as 0 by user code
Port 2.1 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P2.1 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to P2.1 as an output.
Port 2.0 Direction Select Bit
This bit is cleared to 0 by user code to configure the GPIO pin assigned to P2.0 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to P2.0 as an output.
Reserved, this bit is reserved and should be written as 0 by user code
Port 2.6 Data Output
The value written to this bit appears directly on the GPIO pin assigned to P2.6
Port 2.5 Data Output
The value written to this bit appears directly on the GPIO pin assigned to P2.5.
Reserved
These bits are reserved and should be written as 0 by user code
Port 2.1 Data Output
The value written to this bit appears directly on the GPIO pin assigned to P2.1.
Port 2.0 Data Output
The value written to this bit appears directly on the GPIO pin assigned to P2.0.
Reserved, these bits are reserved and should be written as 0 by user code
Port 2.6 Data Input
This bit is a read-only bit that reflects the current status of the GPIO pin assigned to P2.6. User code should write 0 to this bit.
Port 2.5 Data Input
This bit is a read-only bit that reflects the current status of the GPIO pin assigned to P2.5. User code should write 0 to this bit.
Port 2.4 Data Input
This bit is a read-only bit that reflects the current status of the GPIO pin assigned to P2.4. User code should write 0 to this bit.
Reserved, these bits are reserved and should be written as 0 by user code
Port 2.1 Data Input
This bit is a read-only bit that reflects the current status of the GPIO pin assigned to P2.1. User code should write 0 to this bit.
Port 2.0 Data Input
This bit is a read-only bit that reflects the current status of the GPIO pin assigned to P2.0. User code should write 0 to this bit.

0x000000XX
Read/Write
This 32-bit MMR configures the direction of the GPIO pins assigned to Port2 (see Table 52). This register also sets the
output value for GPIO pins configured as outputs and reads the status of GPIO pins configured as inputs.
