NOTES:
1. If the AD0CON4 register is rewritten during A/D conversion, the conversion result will be incorrect.
2. Set bits MPS11 and MPS10 to 00b in the 100-pin package.
3. When the MSS bit in the AD0CON3 register is set to 0 (multi-port sweep mode not used), set bits MPS11 and MPS10 to 00b.
When the MSS bit is set to 1 (multi-port sweep mode used), set bits MPS11 and MPS10 to 01b.

NOTES:
1. When the AD0i register is read by program in DMAC operating mode, the conversion result is incorrect.
2. If the next A/D conversion result is stored before reading the previous result in the AD0i register, the result will be incorrect.
3. Only AD00 register is enabled in DMAC operating mode. The contents of other registers are undefined.
4. When using both DMAC operating mode and 10-bit mode, select a 16-bit transfer for DMAC.
