The relationship between ARM-state and Thumb-state registers
The Thumb-state registers relate to the ARM-state registers in the following way:
•
•
•
•
•
These relationships are shown in Figure 2-5.
Thumb-state r0–r7 and ARM-state r0–r7 are identical
Thumb-state CPSR and SPSRs and ARM-state CPSR and SPSRs are identical
Thumb-state SP maps onto the ARM-state r13
Thumb-state LR maps onto the ARM-state r14
the Thumb-state PC maps onto the ARM-state PC (r15).
