Bits
This register configures GPIO_1. Note, if this pin is to be used as an input, then the output must
be TRI-STATE (bit[0]=’0’) and if used as an output, then the input buffer must be disabled (bit[1]
=’0’).

This register configures GPIO_2. Note, if this pin is to be used as an input, then the output must
be TRI-STATE (bit[0]=’0’) and if used as an output, then the input buffer must be disabled (bit[1]

If any of the GPIO pins are configured as inputs, then reading from this register provides the
values on those input pins.

0
If the GPIO pins are configured as general purpose output pins, then writing to this register has
the effect of transferring the bits in this register to the output buffers of the appropriate GPIO pins.
