WriteToDigitalPort affects other Ports?

[paulb1]

Hi All,

I am using  WriteToDigitalPort to set my DIO as follows

 WriteToDigitalPort (2, "0", 8, 0, 1);

 WriteToDigitalPort (2, "1", 8, 0, 27);

However, when the second line is executed, the first port 0 is reset

Is there something I am doing wrong?

Regards
