turingMachine.md says:
cv5: pulse 2 & 4

SHOULD BE:
cv5: pulse 2 & 3

Because, that's whats in the code

Both are actually saying the same thing. The code:

cv1 - pulse 1 (or config value cv1_pulse_bit)
cv2 - pulse 2 (or config value cv2_pulse_bit)
cv3 - pulse 4 (or config value cv3_pulse_bit)
cv4 - pulse cv1 & cv2
cv5 - pulse cv2 & cv3
cv6 - sequence out

The documentation:

- **cv1:** pulse 1
- **cv2:** pulse 2
- **cv3:** pulse 4
- **cv4:** pulse 1 & 2
- **cv5:** pulse 2 & 4
- **cv6:** sequence out

The markdown file is referring to pulses, but the comment in the code is referring to the CV outputs, which are not the same thing. CV3 outputs Pulse 4, so the comment in the code about CV5 is correct: it outputs Pulse 2 and Pulse 4 (which are individually output on CV2 and CV3).
