The main rule for data access is max(CPL, RPL) ≤ DPL. For code transfers, the rules get considerably more complex -- conforming segments, call gates, and interrupt gates each have different privilege and state validation logic. If all these checks were done in microcode, each segment load would need a cascade of conditional branches: is it a code or data segment? Is the segment present? Is it conforming? Is the RPL valid? Is the DPL valid? This would greatly bloat the microcode ROM and add cycles to every protected-mode operation.

The true flag for useCapture is important. Browser events propagate in two phases: first, they travel down the DOM tree from the root to the target (capture phase), then they bubble up from the target back to the root (bubble phase). By listening in the capture phase, my listener fires before any event listener attached by HotAudio’s player code. Even if fermaw tried to cancel or suppress the event, he’d be too late because the capturing listener always fires first.，推荐阅读旺商聊官方下载获取更多信息
