Setting example:
a.
b. This example repeatedly converts the analog input voltages on the three pins AN0,
X: Don’t care, − : No change
Main routine:
Interrupt routine processing example:
Convert the analog input voltage on the AN3 pin and write the result, to memory
address 1000H using the AD interrupt (INTAD) processing routine.

Enable INTAD and set it to interrupt level 4.
Set pin AN3 to be the analog input channel.
Start conversion in channel fixed single conversion mode.
Read value of ADREG37L and ADREG37H into 16-bit
general-purpose register WA.
Shift contents read into WA six times to right and zero-fill upper
bits.
Write contents of WA to memory address 1000H.
Disable INTAD.
Set pins AN0 to AN2 to be the analog input channels.
Start conversion in channel scan repeat conversion mode.
