GPIO configure and write

F1 = 1

GPIO is output. Data to output is written to F0

F1 = 0

GPIO is input. Data can be read from F0 on readback

Note. When writing to the offset registers, the 14-bit data is right justified (bits F15 and F14 are don’t care). When writing to the X, M or C registers of the AD5363, the

14-bit data is left-justified (bits 1 and 0 of the data word are don’t care).
