this value provide information on the return stack and processor mode. Table 2.16 (p. 28) shows the
EXC_RETURN[3:0] values with a description of the exception return behavior.
The processor sets EXC_RETURN bits[31:4] to 0xFFFFFFF. When this value is loaded into the PC
it indicates to the processor that the exception is complete, and the processor initiates the exception
return sequence.

Exception return gets state from PSP.
Execution uses PSP after return.
b1X11
Reserved.
2.4 Fault handling
Faults are a subset of the exceptions, see Section 2.3 (p. 22) . The following generate a fault:
a bus error on:
an instruction fetch or vector table load
a data access
an internally-detected error such as an undefined instruction or an attempt to change state with a BX
instruction
attempting to execute an instruction from a memory region marked as Non-Executable (XN)
an MPU fault because of a privilege violation or an attempt to access an unmanaged region.
2.4.1 Fault types
Table 2.17 (p. 28) shows the types of fault, the handler used for the fault, the corresponding fault
status register, and the register bit that indicates that the fault has occurred. See Section 4.3.11 (p.
105) for more information about the fault status registers.
