GPIO Output data register is used to control the I\/O state of the I\/O pins. <\/span><\/p>\n

Here only16-bits are used in this register. So, 16 to 31 are reserved, and the 0th-bit position will control the I\/O pin 0. <\/span><\/p>\n

If you write one means corresponding I\/O pin as high and if you write 0 means corresponding I\/O pin as is low. <\/span><\/p>\n

So, these bits can be read and written by software. <\/span>By taking various modes and Pull-up\/Pull-down registers combinations below configuration obtained for a GPIO pin:<\/span><\/span><\/p>\n
