CFK63–CFK60: K6[3:0] pin function selection (D[3:0]) / K6 function select register (0x402C3)
Selects the pins used by the A/D converter.
Write "1": A/D converter
Write "0": Input port
Read: Valid
When an external trigger is used, write "1" to CFK52 to set the K52 pin for external trigger input #ADTRG. Select
the pin used for analog input from among K60 (AD0) through K63 (AD3) by writing "1" to CFK60 through CFK63.
If the function select bit for a pin is set to "0", the pin is set for an input port.
At cold start, CFK is set to "0" (input port). At hot start, CFK retains its state from prior to the initial reset.
