Disable INTAD.
Select AN0 to AN2 as the analog input channels.
Start conversion in channel scan continuous conversion mode.
Enable INTAD and set its priority level to 4.
Select AN3 as the analog input channel.
Start conversion in fixed-channel single conversion mode.
Load the conversion result into 16-bit general-purpose register
Shift the contents of WA 6 bits to the right, padding 0s to the
vacated high-order bits.
Store the contents of WA at address 1800H.
WA from ADREG37L and ADREG37H.
