PEmicro announced the release of its ICDS12ZZ in-circuit debugger software for Freescale's S12Z devices. S12Z MCUs are integrated, mixed-signal devices designed for efficiently developing automotive applications. ICDS12ZZ works in tandem with PEmicro hardware interfaces, such as the Multilink Universal or Multilink Universal FX to debug code in-circuit on Freescale S12Z devices. The ICDS12ZZ expands PEmicro's suite of S12Z software, which includes programming software and interface library routines, which allow custom software designs such as production line testers.
