12 / 147 page  MPC5675K Microcontroller Data Sheet, Rev. 8.1 Introduction NXP Semiconductors 12 • Reception queue possible by setting more than one Rx message buffer with the same ID • Backwards compatible with previous FlexCAN modules • Safety CAN features on 1 CAN module as implemented on MPC5604P 1.6.17 Dual-channel FlexRay controller • Full implementation of FlexRay Protocol Specification 2.1 • Sixty-four configurable message buffers can be handled • Message buffers configurable as Tx, Rx, or RxFIFO • Message buffer size configurable • Message filtering for all message buffers based on FrameID, cycle count, and message ID • Programmable acceptance filters for RxFIFO message buffers • Dual channel, each at up to 10 Mbit/s data rate 1.6.18 Periodic Interrupt Timer (PIT) The PIT module implements the features below: • Four general-purpose interrupt timers • 32-bit counter resolution • Clocked by system clock frequency • 32-bit counter for real time interrupt, clocked from main external oscillator • Can be used for software tick or DMA trigger operation 1.6.19 System Timer Module (STM) The STM implements the features below: • Replicated periphery to provide safety measures respective to high safety integrity levels (for example, SIL 3, ASIL D) • Up-counter with four output compare registers • OS task protection and hardware tick implementation as per current state-of-the-art AUTOSAR requirement 1.6.20 Motor control (MOTC) peripherals The peripherals in this section can be used for general-purpose applications, but are specifically designed for motor control (MOTC) applications. 1.6.20.1 FlexPWM The pulse width modulator module (FlexPWM) contains three PWM channels, each of which is configured to control a single half-bridge power stage. There may also be one or more fault channels. This PWM is capable of controlling most motor types: AC induction motors (ACIM), permanent magnet AC motors (PMAC), both brushless (BLDC) and brush DC motors (BDC), switched (SRM) and variable reluctance motors (VRM), and stepper motors. A FlexPWM module implements the following features: • 16 bits of resolution for center, edge aligned, and asymmetrical PWMs • Maximum operating frequency lower than or equal to platform frequency • Clock source not modulated and independent from system clock (generated via auxiliary PLL) • Fine granularity control for enhanced resolution of the PWM period |
