CONTACT CLOSURE INTERFACE CONTROL
The DS1802 can be configured to operate from contact closure inputs sometimes referred to as
pushbutton control. There exists a total of four physical contact closure terminals on the device package.
When combined with the MODE input, these contact closure inputs provide a total of eight different
contact closure functions. These eight contact closure functions are listed in Table 2.

* independent mode control
** stereo mode control
The MODE input terminal is used to select the mode of wiper control using contact closure. There exist
two modes of wiper control, which include independent mode control and stereo mode control. As shown
in the pin assignment diagram, the contact closure inputs share pins. Input functionality is determined by
the state of the MODE input at power- up.
