ARM DDI 0029G
Store multiple registers
Register
Single register
n registers (n>1)
The store multiple instruction proceeds very much as load multiple instruction, without
the final cycle. The abort handling is much more straightforward as there is no
wholesale overwriting of registers.
The cycle timings are listed in Table 6-13 where:
•
•
Ra is the first register specified
R• are the subsequent registers specified.
