Then in the code RB.1 was made an output and low. Later in the code RB.1 was made an input again. But it still reads as low even though on the I/O panel it is green. If i click on RB.1 and turn it off then back on again, it works correctly (until the next loop). You can see in the picture that RB.1 is green, but in the registers window it says RB is $00 (all off).
