Freescale Semiconductor, Inc.
General Description
• 4 PWM channels with programmable period and duty cycle
– 8-bit 4-channel or 16-bit 2-channel
– Separate control for each pulse width and duty cycle
– Center- or left-aligned outputs
– Programmable clock select logic with a wide range of
frequencies
• Serial interfaces
– Two asynchronous serial communications interfaces (SCI)
– Inter IC bus interface (I²C)
– Synchronous serial peripheral interface (SPI)
• LIM (lite integration module)
– WCR (windowed COP watchdog, real time interrupt, clock
monitor)
– ROC (reset and clocks)
– MEBI (multiplexed external bus interface)
– MMI (memory map and interface)
– INT (interrupt control)
– BKP (breakpoints)
– BDM (background debug mode)
• Two 8-bit ports with key wake-up interrupt
• Clock generation
– Phase-locked loop clock frequency multiplier
– Limp home mode in absence of external clock
– Slow mode divider
– Low power 0.5 to 16 MHz crystal oscillator reference clock
– Option of a Pierce or Colpitts oscillator
