Pull up revision 1.18 (requested by bouyer in ticket #5555):
To disable a channel we need to clear bit 2 or 3, not all other bits but
bit 2 or 3. Thanks to Takeshi Nakayama for catching it.
(With this mistake the code was still working for the first channel, because
the reset of the second channel would disable/enable the first one).
