GPIO4 pull-down
0 = Normal
1 = Pull-down enabled
(Only valid when GPIO4 is set to input. Do not select
pull-up and pull-down at the same time.)
Reset by state machine. Default held in metal mask.
GPIO3 pull-down
0 = Normal
1 = Pull-down enabled
(Only valid when GPIO3 is set to input. Do not select
pull-up and pull-down at the same time.)
Reset by state machine. Default held in metal mask.
GPIO2 pull-down
0 = Normal
1 = Pull-down enabled
(Only valid when GPIO2 is set to input. Do not select
pull-up and pull-down at the same time.)
Reset by state machine. Default held in metal mask.
GPIO1 pull-down
0 = Normal
1 = Pull-down enabled
(Only valid when GPIO1 is set to input. Do not select
pull-up and pull-down at the same time.)
Reset by state machine. Default held in metal mask.
GPIO0 pull-down
0 = Normal
1 = Pull-down enabled
(Only valid when GPIO0 is set to input. Do not select
pull-up and pull-down at the same time.)
Reset by state machine. Default held in metal mask.
GPIO12 Pin Mode

taken after the effect of the GP11_CFG register bit.
1 = GPIO interrupt is both rising and falling edge
triggered.
Reset by state machine.
GPIO10 Pin Mode
0 = GPIO interrupt is rising edge triggered, and is
taken after the effect of the GP10_CFG register bit.
1 = GPIO interrupt is both rising and falling edge
