analogRead() and PuckJS

first test with the NRF52LL module

var ll = require("NRF52LL");

var saadc = ll.saadc({
  channels : [ { // channel 0
    pin:D4,
    gain:1/4,
    tacq:40,
    refvdd:true,
  } ]
});

setInterval(()=>{print(saadc.sample());},1E3);

/* output
[ 4 ]
[ 12 ]
[ 65528 ]
[ 8 ]
[ 4 ]
[ 65524 ]
[ 40 ]
[ 0 ]
[ 12 ]
[ 12 ]
[ 20 ]
[ 16 ]
[ 8 ]
*/

Is the result a 16 bit signed integer and presenting a -32767 to +32767 digital value ?
