Detailed Description
Represents a generic ARM core, with standard application registers.
There are sixteen application registers (including PC, SP, LR) and a PSR. Cortex-M series cores do not support as many core states or shadowed registers as traditional ARM cores, and only support Thumb2 instructions.
