2.10.1.

MCU GPIOs

Each general-purpose input/output (GPIO) pin can be individually configured to operate as an input or output. If

configured as an output, the value driven at the GPIO can be directly written or controlled via a set-clear register.

Additionally, each GPIO pin can be enabled to be used as a trigger source or as interrupt source with a selectable

edge.

2.10.2.

MCU Timer Module

The MCU timer module provides event counting with a 32-bit resolution. It is capable of counting clock events in

timer mode and events from a selectable external trigger signal in counter mode. The external trigger can be

configured to operate on rising or falling edges as well as on a low or high level.

2.10.3.

MCU SPI Master

The integrated SPI is a pure master interface that is used for communication with the SBC chip. The CSN line

must be controlled by software. The SPI clock frequency is configurable by software with a maximum frequency of

half of the system clock frequency.

2.10.4.

MCU LIN Controller

The software-controlled LIN controller provides the logic to handle the LIN bus communication on the frame level

(see Figure 2.3). It consists out of BREAK/SYNC detector, 4-second inactivity timer, and a UART data unit for

frame receiving/transmitting. The LIN wake-up event is detected in the SBC chip and the interrupt on the IRQN

line is generated. The packet-level LIN communication (network layer in Figure 2.2) is handled by the MCU

firmware.
