[−]Enum cortex_a::regs::SPSR_EL1::M::Value

pub enum Value {
    EL0t,
    EL1t,
    EL1h,
}

AArch64 state (Exception level and selected SP) that an exception was taken from. The possible values are:

M[3:0] | State

0b0000 | EL0t 0b0100 | EL1t 0b0101 | EL1h

Other values are reserved, and returning to an Exception level that is using AArch64 with a reserved value in this field is treated as an illegal exception return.

The bits in this field are interpreted as follows:

  • M[3:2] holds the Exception Level.
  • M[1] is unused and is RES 0 for all non-reserved values.
  • M[0] is used to select the SP:
    • 0 means the SP is always SP0.
    • 1 means the exception SP is determined by the EL.
