GPIO configuration options

GPIO Configuration registers #0 through #26 contain the configuration information for each of the 108 GPIO pins. Each GPIO pin can have up to four functions. Configure each pin for the function and direction needed, using the configuration options shown below.

Each GPIO configuration section is set up the same way. This table shows the settings using bits D07:00; the same settings apply to the corresponding bits in D15:08, D23:D16, and D31:24.
