+#### Watchpoint
+
+For this example I'm intercepting `funcPtr` & I want to know who read/write to `x2` so I remove permissions w/ `mprotect`.
+
+```js
+Process.setExceptionHandler(function(exp) {
+  console.error('[!]', JSON.stringify(exp));
+  return true;
+});
+
+Interceptor.attach(funcPtr, {
+  onEnter: function (args) {
+    console.log('onEnter', this.context.x2);
+    Memory.protect(this.context.x2, Process.pointerSize, '---');
+  },
+  onLeave: function (retval) {
+    console.log('onLeave');
+  }
+});
+```
