MCP2515 have SPI interface, but examples from IDF documentation use RX and TX. But where to connect SCK and CS pins? I tried to use it without these pins, but can send or receive any messages. What is the proper way of connecting and initializing MCP2515 with ESP32 and IDF framework?

The same application works on another board using an MCP2515 (QFN) device and an older ESP32-WROVER processor. The pin-outs are the same as the ESP32-WROVER-E processor, so we are any configuration differences for SPI bus between the ESP32-WROVER and ES32-WROVER-E processors?
