GPIO5_DATA

GPIO5 Pin Configuration: Reflects the level of GPIO5. 0 = Low, 1 = High. (Note)

GPIO4_DATA

GPIO4 Pin Configuration: Reflects the level of GPIO4. 0 = Low, 1 = High. (Note)

GPIO3_DATA

GPIO3 Pin Configuration: Reflects the level of GPIO3. 0 = Low, 1 = High. (Note)

GPIO2_DATA

GPIO2 Pin Configuration: Reflects the level of GPIO2. 0 = Low, 1 = High. (Note)

GPIO1_DATA

GPIO1 Pin Configuration: Reflects the level of GPIO1. 0 = Low, 1 = High. (Note)

GPIO0_DATA

GPIO0 Pin Configuration: Reflects the level of GPIO0. 0 = Low, 1 = High. (Note)

Note: Bits [7:0] contain the direct values of the GPIO pins. Write operations can be done only for GPIOs that are defined as outputs.

Reads from these bits read the last written value if the GPIO pin is configured as an output. The direction of the GPIO pins is con-

trolled through Offset 438h[7:0].

GPIO4_PUPD

GPIO4 Pin Pull-up or Pull-down Mode: 0 = Pull-down mode; 1 = Pull-up mode. (Note)

GPIO3_PUPD

GPIO3 Pin Pull-up or Pull-down Mode: 0 = Pull-down mode; 1 = Pull-up mode. (Note)

GPIO2_PUPD

GPIO1_PUPD

GPIO1 Pin Pull-up or Pull-down Mode: 0 = Pull-down mode; 1 = Pull-up mode. (Note)

GPIO0_PUPD

GPIO0 Pin Pull-up or Pull-down Mode: 0 = Pull-down mode; 1 = Pull-up mode. (Note)

GPIO7_MODE

GPIO7 Pin Mode: 0 = Normal mode; 1 = Weak pull-up or weak pull-down mode.

GPIO6_MODE

GPIO6 Pin Mode: 0 = Normal mode; 1 = Weak pull-up or weak pull-down mode.

GPIO5_MODE

GPIO5 Pin Mode: 0 = Normal mode; 1 = Weak pull-up or weak pull-down mode.

GPIO3 Pin Mode: 0 = Normal mode; 1 = Weak pull-up or weak pull-down mode.

GPIO2_MODE

GPIO2 Pin Mode: 0 = Normal mode; 1 = Weak pull-up or weak pull-down mode.

GPIO1_MODE

GPIO1 Pin Mode: 0 = Normal mode; 1 = Weak pull-up or weak pull-down mode.

GPIO0_MODE

GPIO0 Pin Mode: 0 = Normal mode; 1 = Weak pull-up or weak pull-down mode.

7GPIO7_TYPE

GPIO7 Pin Type: 0 = Input; 1 = Output.

6GPIO6_TYPE

GPIO6 Pin Type: 0 = Input; 1 = Output.

5GPIO5_TYPE

GPIO5 Pin Type: 0 = Input; 1 = Output.

4GPIO4_TYPE

GPIO4 Pin Type: 0 = Input; 1 = Output.

3GPIO3_TYPE

GPIO3 Pin Type: 0 = Input; 1 = Output.

2GPIO2_TYPE

GPIO2 Pin Type: 0 = Input; 1 = Output.

1GPIO1_TYPE

GPIO1 Pin Type: 0 = Input; 1 = Output.

0GPIO0_TYPE

GPIO0 Pin Type: 0 = Input; 1 = Output.

Note: To enable the pull-up or pull-down mode function, the corresponding GPIO pin’s MODE bit must be set to 1, and the correspond-

ing TYPE bit must enable it as an output (i.e., be set to 1).
