PB6 voltage level

Dear All,

In an application I'm writing I'm having problems using PB.6 as a push-pull output. I get 1.7V without load on the output when I'm expecting 5V! This would not be a problem but when I try to drive a transistor with pin PB.6 there's not enough forward bias to turn the transistor on! Any Ideas anyone?

Hmmm. Have lifted some of the legs on the ST7 and it seems only some of them are outputting 5V when turned on.

Would the issue I describe be because the pins that I am using must be high sink in order to drive a transistor base?
