I'm using an AT90USB162 and want to use the built-in comparator. The datasheet says that there is a
register "Digital Input Disable Registers (DIDR1)" to disable the digital input circuit for the two analog
But DIDR1 isn't listed in the Register Summary in the datasheet and it is not defined in the
iousbxx2.h file in Studio5.
Does this register actually exist?
If so, how is it accessed?
