I hope with the DAC6 output a 0V~2V Vpp PWM waveform.(CY8C27443_24PVXI)

   

The DAC6 module to connect AnalogOutBuf_3 to P02 output.

   

But,DAC6 Initializes the output overshoot.

   

I hope P02 initialize output has been 0V.

   

What should I do?

   

Now operating:

   

    DAC6_1_WriteStall(0);
    DAC6_1_Start(DAC6_1_FULLPOWER);

   

 

   

Module Configuration

   

DAC6_1:

   

1.ASC23 

   

2.AnalogOutBus_3

   

3.Normal

   

4.OffsetBinary

   

 

   

P02:

   

AnalogOutBuf_3

   

High Z Analog

The analog output buffers can go only to roughly 1.2V from the VSS pin. This is detailed in the datasheet for CY8C27443 in Table 19 5-V DC Analog Output Buffer Specifications.
