This Schmitt-triggered input from the disk drive is
active low when the head is positioned over the
beginning of a track marked by an index hole.
Clear To Send is the modem control input.
PWM2 Output where its frequency range is
183Hz~46.875KHz. It can support various
applications such as manual fan control, and
backlight brightness control.
