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
DisableInt
0

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.
