GPIO Port2 Data Register
Name:
GP2DAT
Address:
0xFFFF0D40
Default Value:
0x000000XX
Access:
Read/write
Function:
This 32-bit MMR configures the direction of the GPIO pins assigned to Port2 (see Table 57). This register also sets the
output value for GPIO pins configured as outputs and reads the status of GPIO pins configured as inputs.
Table 63. GP2DAT MMR Bit Designations
Bit
Description
31
Reserved. This bit is reserved and should be written as 0 by user code.
30
Port2.6 direction select bit.
Set to 1 by user code to configure the GPIO pin assigned to Port2.6 as an output.
Cleared to 0 by user code to configure the GPIO pin assigned to Port2.6 as an input.
29
Port2.5 direction select bit.
Set to 1 by user code to configure the GPIO pin assigned to Port2.5 as an output. This configuration is used to support
diagnostic write capability to the high voltage I/O pins.
Cleared to 0 by user code to configure the GPIO pin assigned to Port2.5 as an input.
28
Port2.4 direction select bit.
Set to 1 by user code to configure the GPIO pin assigned to Port2.4 as an output.
Cleared to 0 by user code to configure the GPIO pin assigned to Port2.4 as an input. This configuration is used to support
diagnostic readback capability from the high voltage I/O pins (see HVCFG1[2:0]).
27 to 26
Reserved. These bits are reserved and should be written as 0 by user code.
25
Port2.1 direction select bit.
Set to 1 by user code to configure the GPIO pin assigned to Port2.1 as an output.
Cleared to 0 by user code to configure the GPIO pin assigned to Port2.1 as an input.
24
Port2.0 direction select bit.
Set to 1 by user code to configure the GPIO pin assigned to Port2.0 as an output.
Cleared to 0 by user code to configure the GPIO pin assigned to Port2.0 as an input.
23
Reserved. This bit is reserved and should be written as 0 by user code.
22
Port2.6 data output. The value written to this bit appears directly on the GPIO pin assigned to Port2.6.
21
Port2.5 data output. The value written to this bit appears directly on the GPIO pin assigned to Port2.5.
20 to 18
Reserved. These bits are reserved and should be written as 0 by user code.
17
Port2.1 data output. The value written to this bit appears directly on the GPIO pin assigned to Port2.1.
16
Port2.0 data output. The value written to this bit appears directly on the GPIO pin assigned to Port2.0.
15 to 7
Reserved. These bits are reserved and should be written as 0 by user code.
6
Port2.6 data input. This bit is a read only bit that reflects the current status of the GPIO pin assigned to Port2.6. User code
should write 0 to this bit.
5
Port2.5 data input. This bit is a read only bit that reflects the current status of the GPIO pin assigned to Port2.5. User code
should write 0 to this bit.
4
Port2.4 data input. This bit is a read only bit that reflects the current status of the GPIO pin assigned to Port2.4. User code
should write 0 to this bit.
3 to 2
Reserved. These bits are reserved and should be written as 0 by user code.
1
Port2.1 data input. This bit is a read only bit that reflects the current status of the GPIO pin assigned to Port2.1. User code
should write 0 to this bit.
0
Port2.0 data input. This bit is a read only bit that reflects the current status of the GPIO pin assigned to Port2.0. User code
should write 0 to this bit.
