Because I never figured out a way to *place* an array at
the known physical address in memory where I want it,
such as 0xFFE0, or whatever the address of, say, the
ADC result registers may be in the microcontroller.

Maybe there is a simpler way to do things like this.
But I never got it. Any advice would be welcome.

Best regards, Chris.
