How many transistors does the 80286 have?

The Intel 80286, introduced on 1 February 1982, is a 16-bit x86 microprocessor with 134,000 transistors. Like its contemporary simpler cousin, the 80186, it can correctly execute most software written for the earlier Intel 8086 and 8088 .

What is the use of 80286 protected mode flag?

Protection Enable flag places the 80286 in protected mode, if set. This can only be cleared by resetting the CPU. If the Monitor Processor Extension flag is set, allows WAIT instruction to generate a processor extension not present exception. Processor Extension Emulator flag if set, causes a processor extension absent exception and permits
