INT (interrupt module)
— Seven levels of nested interrupts
— Flexible assignment of interrupt sources to each interrupt level.
— External non-maskable high priority interrupt (XIRQ)
— The following inputs can act as Wake-up Interrupts
MMC (module mapping control)
DBG (debug module)
— Monitoring of CPU bus with tag-type or force-type breakpoint requests
— 64 x 64-bit circular trace buffer captures change-of-flow or memory access information
BDM (background debug mode)
OSC_LCP (oscillator)
— Low power loop control Pierce oscillator utilizing a 4MHz to 16MHz crystal
— Good noise immunity
— Full-swing Pierce option utilizing a 2MHz to 40MHz crystal
— Transconductance sized for optimum start-up margin for typical crystals
IPLL (Internally filtered, frequency modulated phase-locked-loop clock generation)
— No external components required
— Configurable option to spread spectrum for reduced EMC radiation (frequency modulation)
CRG (clock and reset generation)
— COP watchdog
— Real time interrupt
— Clock monitor
— Fast wake up from STOP in self clock mode
Memory Options
