The cortex_m3 has a itm (instruction trace, serial output) that on all current devices is multiplexed with jtag TMS. Because of this we need to use swi to access this info. Also you get acks back from the swi so speed does not matter as the clock is in sync, similar to the old jtag rclk. Also in future we could add support for the trace port - similar to old arm etm.
