GPIO Port Data Register
Name:
GPDAT
Address:
0xFFFF0D10
Default Value:
0x000000FF
Access:
Read/write
Function:
This 32-bit MMR configures the direction of the GPIO pins. This register also sets the output value for GPIO pins
configured as outputs and reads the status of GPIO pins configured as inputs.

Bit
Description
31 to 30
Reserved. These bits are reserved and should be written as 0 by user code.
29
Port 0.5 direction select bit.
This bit is cleared to 0 by user code to configure the GPIO pin assigned to Port 0.5 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to Port 0.5 as an output.
28
Port 0.4 direction select bit.
This bit is cleared to 0 by user code to configure the GPIO pin assigned to Port 0.4 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to Port 0.4 as an output.
27
Port 0.3 direction select bit.
This bit is cleared to 0 by user code to configure the GPIO pin assigned to Port 0.3 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to Port 0.3 as an output.
26
Port 0.2 direction select bit.
This bit is cleared to 0 by user code to configure the GPIO pin assigned to Port 0.2 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to Port 0.2 as an output.
25
Port 0.1 direction select bit.
This bit is cleared to 0 by user code to configure the GPIO pin assigned to Port 0.1 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to Port 0.1 as an output.
24
Port 0.0 direction select bit.
This bit is cleared to 0 by user code to configure the GPIO pin assigned to Port 0.0 as an input.
This bit is set to 1 by user code to configure the GPIO pin assigned to Port 0.0 as an output.
23 to 22
Reserved. These bits are reserved and should be written as 0 by user code.
21
Port 0.5 data output. The value written to this bit appears directly on the GPIO pin assigned to Port 0.5.
20
Port 0.4 data output. The value written to this bit appears directly on the GPIO pin assigned to Port 0.4.
19
Port 0.3 data output. The value written to this bit appears directly on the GPIO pin assigned to Port 0.3.
18
Port 0.2 data output. The value written to this bit appears directly on the GPIO pin assigned to Port 0.2.
17
Port 0.1 data output. The value written to this bit appears directly on the GPIO pin assigned to Port 0.1.
16
Port 0.0 data output. The value written to this bit appears directly on the GPIO pin assigned to Port 0.0.
15 to 6
Reserved. These bits are reserved and should be written as 0 by user code.
5
Port 0.5 data input. This bit is a read-only bit that reflects the current status of the GPIO pin assigned to Port 0.5. User code
should write 0 to this bit.
4
Port 0.4 data input. This bit is a read-only bit that reflects the current status of the GPIO pin assigned to Port 0.4. User code
should write 0 to this bit.
3
Port 0.3 data input. This bit is a read-only bit that reflects the current status of the GPIO pin assigned to Port 0.3. User code
should write 0 to this bit.
2
Port 0.2 data input. This bit is a read-only bit that reflects the current status of the GPIO pin assigned to Port 0.2. User code
should write 0 to this bit.
1
Port 0.1 data input. This bit is a read-only bit that reflects the current status of the GPIO pin assigned to Port 0.1. User code
should write 0 to this bit.
0
Port 0.0 data input. This bit is a read-only bit that reflects the current status of the GPIO pin assigned to Port 0.0. User code
should write 0 to this bit.
