Description
When this bit is 1, Pin 42 is enabled as a general ? purpose I/O pin (GPIO16);
otherwise it is the THERM output.
Writing a 1 to this bit clears the CI latch. This bit is cleared by writing a 0 to it.
When this bit is 0, V REF (Pin 24) outputs 1.82 V, otherwise, it outputs 2.5 V.
Undefined, reads back 0.
When this bit is 0, GPIO16 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO16 is active low; otherwise, it is active high.
