General Description

Technical Data MC68HC912DT128A — Rev 4.0

28 General Description MOTOROLA

• 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 (I

– 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
