USB6501 Digital output to trigger 5vdc relay

Hi All,

I am using USB6501 to trigger a 5vdc relay 

when i pull high, i not see the relay triggered. 

after troubleshoot i found that my USB6501 at port P0.0 only give 3.3 v instead of 5v.

are they any setting that i need to do to increase the voltage from 3.3v to 5v?

thanks in advance
