19.14.5 WPUx
Important: 
            
- The weak pull-up device is automatically disabled if the pin is configured as an output, but this register remains unchanged
- If MCLRE = 1, the weak pull-up on MCLR pin is always enabled and the corresponding WPU bit is not affected
- Refer to the “Pin Allocation Table” for details about pin availability per port
- Unimplemented bits will read back
                  as ‘0’
