Thumb Instruction Set Overview
Table 11-2
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
