Thumb Instruction Set Overview
Table 11-2.
The Thumb instruction set is a re-encoded subset of the ARM instruction set.
The Thumb instruction set is divided into:
In Thumb mode, eight general-purpose registers, R0 to R7, are available that are the same
physical registers as R0 to R7 when executing ARM instructions. Some Thumb instructions also
access to the Program Counter (ARM Register 15), the Link Register (ARM Register 14) and the
