NOTES:
1. When the AD0CON2 register is rewritten during the A/D conversion, the conversion result is
indeterminate.
2. When the MSS bit in the AD0CON3 register is set to "1" (multi-port sweep mode enabled), set the
APS1 and APS0 bits to "012".
3. The APS1 and APS0 bits can be set to "102" or "112" in single-chip mode only.
