GPIO_USER_CONTROL.GPIO8_TO_15_OUT
Write these bits to define the level on a GPIO output pin when configured for user output control.
TRIGGER: Writing to this byte triggers a read and activation in hardware of all the bytes of the GPIO_USER_CONTROL module.
GPIO4_DRIVE_LEVEL[4] R/W 0 GPIO pin 4 drive level.
Valid only if GPIO_FUNCTION is disabled and 'gpio_control_dir' is output.
0 = drive low
1 = drive high
GPIO3_DRIVE_LEVEL[3] R/W 0 GPIO pin 3 drive level.
Valid only if GPIO_FUNCTION is disabled and 'gpio_control_dir' is output.
0 = drive low
1 = drive high
GPIO2_DRIVE_LEVEL[2] R/W 0 GPIO pin 2 drive level.
Valid only if GPIO_FUNCTION is disabled and 'gpio_control_dir' is output.
0 = drive low
1 = drive high
GPIO1_DRIVE_LEVEL[1] R/W 0 GPIO pin 1 drive level.
Valid only if GPIO_FUNCTION is disabled and 'gpio_control_dir' is output.
0 = drive low
1 = drive high
GPIO0_DRIVE_LEVEL[0] R/W 0 GPIO pin 0 drive level.
Valid only if GPIO_FUNCTION is disabled and 'gpio_control_dir' is output.
0 = drive low
1 = drive high
