nRF24LE1 Preliminary Product Specification
The input and output options of each pin are configured in the PxCON registers. The PxCON registers
have to be written once per pin (one write operation to the PxCON register configures the input/output
options of a selected pin in the port).
To read the current input or output options for a pin, you first need to perform a write operation to retrieve
the desired bit address and option type (input or output).
