You are using the wrong option. "Pause" has a different meaning in the slider. Auto-option defines if the slider is autoplaying.
$(".rslides_home").responsiveSlides({
auto: false
});
Here are the defined options for the slider. As you can see, the "pause" option is used when you want the slider to stop when hovered.
$(".rslides").responsiveSlides({
auto: true, // Boolean: Animate automatically, true or false
speed: 500, // Integer: Speed of the transition, in milliseconds
timeout: 4000, // Integer: Time between slide transitions, in milliseconds
pager: false, // Boolean: Show pager, true or false
nav: false, // Boolean: Show navigation, true or false
random: false, // Boolean: Randomize the order of the slides, true or false
pause: false, // Boolean: Pause on hover, true or false
pauseControls: true, // Boolean: Pause when hovering controls, true or false
prevText: "Previous", // String: Text for the "previous" button
nextText: "Next", // String: Text for the "next" button
maxwidth: "", // Integer: Max-width of the slideshow, in pixels
navContainer: "", // Selector: Where controls should be appended to, default is after the 'ul'
manualControls: "", // Selector: Declare custom pager navigation
namespace: "rslides", // String: Change the default namespace used
before: function(){}, // Function: Before callback
after: function(){} // Function: After callback
});
