Damn, how do you get the ascii art to come out correctly? I tried doing it in a text editor this time and it looked good in preview, but then posted like garbage. I'll try to explain what I did.
Nand 1 has Pic and enable as its inputs. Nand 2 has RC and and NOT_enable as its inputs Nand 3 has its inputs tied together and enable as its input and NOT_enable as its output. Nand 4 has its inputs connected to the oputputs of NAND 1 and NAND 2. Nand 4 output goes to servo. This way a 1 on enable allows 1 path and a 0 allows the other path. The pwm gets inverted twice so it is back to normal. All in1 chip. Does this make sense? Also copy the drawing above and place it in a text editor (I used outlook set in plain text mode) and the drawing looks ok.
