See the glossary at:

AArch32 state
        The ARM 32-bit Execution state that uses 32-bit general purpose
        registers, and a 32-bit program counter (PC), stack pointer
        (SP), and link register (LR). AArch32 Execution state provides a
        choice of two instruction sets, A32 and T32.
        
        In implementations of versions of the ARM architecture before
        ARMv8, and in the ARM R and M architecture profiles, execution
        is always in AArch32 state.
