Modes and Exception Handling
Table 11-1.
Registers R0 to R7 are unbanked registers, thus each of them refers to the same 32-bit physical
register in all processor modes. They are general-purpose registers, with no special uses man-
aged by the architecture, and can be used wherever an instruction allows a general-purpose
register to be specified.
Registers R8 to R14 are banked registers. This means that each of them depends of the current
processor mode.
For further details, see the ARM Architecture Reference Manual, Rev. DDI0100E.
All exceptions have banked registers for R14 and R13.
After an exception, R14 holds the return address for exception processing. This address is used
both to return after the exception is processed and to address the instruction that caused the
exception.
R13 is banked across exception modes to provide each exception handler with a private stack
pointer.
The fast interrupt mode also banks registers 8 to 12 so that interrupt processing can begin with-
out the need to save these registers.
