ARM has a “Load/Store” architecture since all instructions (other than the load and store instructions) must use register operands. 4300 example projects including for STMicroelectronics evaluation boards; Support for 4 Gbyte applications in ARM® and Thumb® mode; Each function can be compiled in ARM® or Thumb® mode; VFP Vector Floating Point co-processor code generation; Intrinsic NEON™ support; Hardware debugging support: STMicroelectronics ST-LINK V2 : Supports STM32 devices

This example code starts in ARM state. The first instruction adds the address specified in PC plus 1 to R3 and then branches to the address in R3. This will cause a switch to Thumb state, because the LSB (least significant bit) is 1 and therefore not 4 byte aligned.
