when I use two MCU S32K for SPI communication, and one is master
other is slave, what is the peripheral circuit for the two SPI connection.
Hi bettyshen,
No special circuit is required.
Please refer to the S32K1xx DS rev12, Section 6.5.2 for the LPSPI electrical specifications.
AN5426 provides Hardware Design Guidelines for S32K1xx Microcontrollers.
