Hello,
I have a question about REFCON and DACxCON[1:0] bit.

I want to use the external refernce source for ADC and DAC.

Pls teach me the value of REFCON and DACxCON[1:0] bit.

 

The datasheet (P.35) describes,below.

"To connect an external reference source to the ADuC7023,configure REFCON = 0x00."

 

However, at Table41,
REFCON Bit0 = 1 when ADC and DAC work with an external reference.

Which is correct?.

Thank you.

Regards,
Kou
