Which instruction format does Cortex-R support,encoding A1 orA2?

I see it support encoding T2 for Thumb-2 instruction set.But which instruction format does Cortex-R support for ARM instruction,encoding A1 orA2?

  • Now I just talk about ARMv7 Architecture.

    The picture above shows that ARMv7 Architecture support both encoding A1 and A2.

    So I think MOV should be with 12bit constant.

    But in my project I did assemble a MOV with the 16-bit constant,and CCS didn't shows any errors.Why?
