NOTES:
1. If the AD0CON1 register is rewritten during A/D conversion, the conversion result will be incorrect.
2. Bits SCAN1 and SCAN0 are enabled in single sweep mode, repeat sweep mode 0, 1, multi-port single sweep mode, and multi-
3. These are prioritized pins used for A/D conversion when the MD2 bit is set to 1.
4. When the MSS bit in the AD0CON3 register is set to 1 (multi-port sweep mode used);
5. Refer to the note for the CKS0 bit in the AD0CON0 register.
6. Bits OPA1 and OPA0 can be set to 01b or 10b in one-shot mode and repeat mode. Set these bits to 00b or 11b in other modes.
7. Do not set the VCUT bit to 0 during A/D conversion. Even if the VCUT bit is set to 0, VREF remains connected to the D/A
8. When the VCUT bit is set to 1 from 0, wait for 1 μ s or more to start the A/D conversion.
