4.4 DISPLAY CONTENT INTEGRITY CHECKER (DCIC) The goal of the DCIC is to verify that a safety-critical information sent to a display is not corrupted.

Such a verification is mandatory for warning icons in the instrument cluster of a car, to comply with the ASIL B (Automotive Safety Integrity Level B) specification. It is also required in other safety-sensitive systems.



Using external muxing DCIC can monitor either one of the IPU display port outputs or feedback signals going from IO pads of Parallel display interface.

4.5 ENHANCED CONFIGURABLE SPI (ECSPI) The Enhanced Configurable Serial Peripheral Interface (ECSPI) is a full-duplex, synchronous, four-wire serial communication block.

The ECSPI contains a 64 x 32 receive buffer (RXFIFO) and a 64 x 32 transmit buffer (TXFIFO). With data FIFOs, the ECSPI allows rapid data communication with fewer software interrupts.

4.8 FLEXIBLE CONTROLLER AREA NETWORK (FLEXCAN)

The Flexible Controller Area Network (FLEXCAN) module is a communication controller implementing the CAN protocol according to the CAN 2.0B protocol specification. The CAN protocol was primarily designed to be used as a vehicle serial data bus meeting the specific requirements of this field: real-time processing, reliable operation in the EMI environment of a vehicle, cost-effectiveness and required bandwidth. The FLEXCAN module is a full implementation of the CAN protocol specification, which supports both standard and extended message frames. 64 Message Buffers are supported.

4.9 GENERAL PURPOSE INPUT/OUTPUT (GPIO)

The GPIO general-purpose input/output peripheral provides dedicated general-purpose pins that can be configured as either inputs or outputs.

When configured as an output, it is possible to write to an internal register to control the state driven on the output pin. When configured as an input, it is possible to detect the state of the input by reading the state of an internal register. In addition, the GPIO peripheral can produce CORE interrupts.

4.10 GENERAL PURPOSE TIMER (GPT) The GPT has a 32-bit up-counter. The timer counter value can be captured in a register using an event on an external pin. The capture trigger can be programmed to be a rising or/and falling edge. The GPT can also generate an event on the DO_CMPOUTn pins and an interrupt when the timer reaches a programmed



value. The GPT has a 12-bit prescaler, which provides a programmable clock frequency derived from multiple clock sources.
