Chapter 1 MC9S12XHZ Family Device Overview
• 8 PWM (pulse-width modulator) channels
— Programmable period and duty cycle
— 8-bit 8-channel or 16-bit 4-channel
— Separate control for each pulse width and duty cycle
— Center-aligned or left-aligned outputs
— Programmable clock select logic with a wide range of frequencies
— Fast emergency shutdown input
• Two 1-Mbps, CAN 2.0 A, B software compatible modules
— Five receive and three transmit buffers
— Flexible identifier filter programmable as 2 x 32 bit, 4 x 16 bit, or 8 x 8 bit
— Four separate interrupt channels for Rx, Tx, error, and wake-up
— Low-pass filter wake-up function
— Loop-back for self-test operation
• Two IIC (Inter-IC bus) Modules
— Compatible with IIC bus standard
— Multi-master operation
— Broadcast mode
• Serial interfaces
— Two asynchronous serial communication interfaces (SCI) with additional LIN support and
selectable IrDA 1.4 return-to-zero-inverted (RZI) format with programmable pulse width
— Synchronous Serial Peripheral Interface (SPI)
• Liquid crystal display (LCD) driver with variable input voltage
— Configurable for up to 32 frontplanes and 4 backplanes or general-purpose input or output
— 5 modes of operation allow for different display sizes to meet application requirements
— Unused frontplane and backplane pins can be used as general-purpose I/O
• PWM motor controller (MC) with 24 high current drivers
— Each PWM channel switchable between two drivers in an H-bridge configuration
— Left, right and center aligned outputs
— Support for sine and cosine drive
— Dithering
— Output slew rate control
• Six stepper stall detectors (SSD)
— Full step control during return to zero
— Voltage detector and integrator / sigma delta converter circuit
— 16-bit accumulator register
— 16-bit modulus down counter
