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.

In effect, we use setraw to make sure our raw character input goes straight into our process (without echoing or buffering or anything), and then reading and echoing the character-codes we see until 3 appears (which is CTRL-C, the common command for existing a REPL). Since we've turned on tty.setraw print doesn't reset the cursor to the left anymore, so we need to manually move left with \u001b[1000D after each print.,这一点在91视频中也有详细论述
