BIT DESCRIPTION
This bit controls the GPIO0 pin. When cleared, GPIO0 pin is an input. When set, GPIO0 pin is an output. This bit is cleared on reset.
This bit controls the GPIO1 pins. When cleared, GPIO1 pin is an input. When set, GPIO1 pin is an output. This bit is cleared on reset.
When read, this bit shows the status values of the GPIO0 pin. When written into, this bit will drive the GPIO0 pin if GPIO0Ctrl is set, and GPIO0 pin functions as an output.
When read, this bit shows the status values of the GPIO1 pin. When written into, this bit will drive the GPIO1 pin if GPIO1Ctrl is set, and GPIO1 pin functions as an output.
Reserved for future use. Should be set to 0.
