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.
