/*
* When branching to an address that has bits [31:28] == 0xf an exception return
* occurs. Bits [27:5] are reserved (SBOP). If the processor implements the FP
* extension Bit [4] defines if the exception frame has space allocated for FP
* state information, SBOP otherwise. Bit [3] defines the mode that is returned
* to (0 -> handler mode; 1 -> thread mode). Bit [2] defines which sp is used
* (0 -> msp; 1 -> psp). Bits [1:0] are fixed to 0b01.
