1. “Detailed Guide on Using FlexIO Module in S32K1xx MCU”
The FlexIO module of S32K1xx MCU consists of several serial shift registers and timers, along with IO pins and a configurable control status register:
The integrated timers, serial shift registers, and pin resources of the FlexIO module in S32K1xx MCU are shown in the table below:
The FlexIO module can be flexibly configured for use as serial communication peripherals, such as UART, I2C, SPI, I2S, and LIN controllers, thus providing additional serial communication peripheral modules.
The table below lists the FlexIO resources required for configuring some common serial communication peripherals:
