Which of A/D and D/A converter are done at the same time is the priority?

Latest Updated:03/23/2009

Question:

A/D input pins of SH7206 are multiplexed with D/A pins. When both A/D converter and D/A converter are executed at the same time, which of them has a priority?

Answer:

For PF6/AN6/DA0 pin and PF7/AN7/DA1 pin of SH7206, A/D input pin is multiplexed with D/A output pin.

A/D converter and D/A converter cannot be executed at the same time by using these pins.

If A/D converter and D/A converter are executed at the same time, the A/D input signal collides with the D/A output signal, and there is a possibility to cause the pins destruction. So, do not execute A/D converter and D/A converter at the same time by using PF6/AN6/DA0 pin and PF7/AN7/DA1 pin.
