Webmstatus: The low 12 bits of this register store a 4-element stack of privilege/user mode (PRV) and interrupt enable (IE) bits. Each stack element is 3 bits wide. For example, mstatus[2:0] corresponds to the top of the stack, and contains the current PRV and IE bits. Specifically, mstatus[0] is the IE bit, and interrupts are enabled if IE = 1.
