Please excuse the +// clutter. Also, there is no current way to detect the width of the +// specified GPIO bank, so the user must specify the width with the --bits +// flag if more than 11 bits. +// +// GPIO Testing: +// For testing, GPIO bits are set as follows: +// GPIO[0] = ATR output 1 at idle +// GPIO[1] = ATR output 1 during RX +// GPIO[2] = ATR output 1 during TX +// GPIO[3] = ATR output 1 during full duplex +// GPIO[4] = output +// GPIO[n:5] = input (all other pins) +// The testing cycles through idle, TX, RX, and full duplex, dwelling on each +// test case (default 2 seconds), and then comparing the readback register with +// the expected values of the outputs for verification.

Outputs can be +// physically looped back to inputs to manually verify the inputs. +// +// GPIO Bit Banging: +// GPIO banks have the standard registers of DDR for data direction and OUT +// for output values. Users can bit bang the GPIO bits by using this example +// with the --bitbang flag and specifying the --ddr and --out flags to set the +// values of the corresponding registers. The READBACK register is +// continuously read for the duration of the dwell time (default 2 seconds) so +// users can monitor changes on the inputs. +// +// Automatic Transmit/Receive (ATR): +// In addition to the standard DDR and OUT registers, the GPIO banks also +// have ATR (Automatic Transmit/Receive) control registers that allow the +// GPIO pins to be automatically set to specific values when the USRP is +// idle, transmitting, receiving, or operating in full duplex mode. The +// description of these registers is below: +// CTRL - Control (0=manual, 1=ATR) +// ATR_0X - Values to be set when idle +// ATR_RX - Output values to be set when receiving +// ATR_TX - Output values to be set when transmitting +// ATR_XX - Output values to be set when operating in full duplex +// This code below contains examples of setting all these registers.
