When this bit is 0, GPIO1 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO1 is active low; otherwise it is active high.
When this bit is 0, GPIO2 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO2 is active low; otherwise, it is active high.
When this bit is 0, GPIO3 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO3 is active low; otherwise, it is active high.
When this bit is 0, GPIO4 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO4 is active low; otherwise, it is active high.
When this bit is 0, GPIO5 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO5 is active low; otherwise, it is active high.
When this bit is 0, GPIO6 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO6 is active low; otherwise, it is active high.
When this bit is 0, GPIO7 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO7 is active low; otherwise, it is active high.
When this bit is 0, GPIO8 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO8 is active low; otherwise, it is active high.
When this bit is 0, GPIO9 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO9 is active low; otherwise, it is active high.
When this bit is 0, GPIO10 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO10 is active low; otherwise, it is active high.
When this bit is 0, GPIO11 is configured as an input; otherwise, it is an output.
When this bit is 0, GPIO11 is active low; otherwise, it is active high.
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
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.
