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.

GPIO7_TYPE

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

GPIO6_TYPE

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

GPIO5_TYPE

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

GPIO4_TYPE

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

GPIO3_TYPE

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

GPIO2_TYPE

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

GPIO1_TYPE

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

GPIO0_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).
