K22P144M120SF5V2RM.pdf, dated Mar 2015, Revision 5, says that the 12-bit DAC has only 2 12-bit data registers, DAT0L/H and DAT1L/H. The RM also has references to 16 data registers that were probably left over when the RM was edited. However, when trying to port my DAC code from the TWR K40, which worked with the 16 data registers, it also works in the MK22FX512A. And the debugger sees all 16 data registers, DAT0L/H thru DAT15L/H. Is the RM wrong? Or should I not be using all 16 data registers?
