Trying doing it in start().
P2DIR |= 1;
P2SEL |= 1;
It should be the equivalent of the above two lines, which I know do work.

I found in the datasheet that i have to use port 20. I have to select the
ACLK and then to selesct the direction.
How i do this?
I try to use the General IO component on port 20 and write in the init of
my application :
call CLK_PIN.selectModuleFunc();
call CLK_PIN.makeOutput();
But nothing appens...
What can i do?
