Analogue Input Sampling
4 times oversampling is scheduled with samples taken every 250 usec,
providing measurements every 1 msec.
The following inputs are sampled at 250 usec, with microsecond offsets as
shown in the table:
Offsets
0.0 usec +1.5 usec +3.1 usec
0.0 usec AT1 AV1 AV15
+9.3 usec AT2 AV2 AV16
+20.9 usec AT3 AV3 AV17
+30.1 usec AT4 AV4 AV18
+39.4 usec AT5 AV5 AV19
+51.0 usec AT6 AV6 AV20
+60.3 usec AT7 AV7 AV21
+71.9 usec AT8 AV8 AV22
+81.1 usec N/A AV9 AV23
+90.4 usec 8VSEN AV10 AV24
+102.0 usec 5VSEN AV11 INT TEMP
+111.3 usec ACCELX AV12 SPD1
+122.9 usec ACCELY AV13 SPD2
+132.1 usec ACCELZ AV14 SPD3
+141.4 usec N/A BAT VOLTS SPD4
