R0
; Generate branch target address
; and set bit 0 high - hence
; arrive in THUMB state.
; Branch and change to THUMB
; state.
; Assemble subsequent code as
; THUMB instructions
; Generate branch target to word aligned address
; - hence bit 0 is low and so change back to ARM state.
; Branch and change back to ARM state.
; Word align
; Assemble subsequent code as ARM instructions
