WebMar 16, 2024 · SPI has four modes of operation, based on two parameters: clock polarity (CPOL) and clock phase (CPHA). Master and slave must use the same mode to communicate articulately. If CPOL is zero, then SCLK is normally low, and the first clock edge is a rising edge. If CPOL is one, SCLK is normally high, and the first clock edge is a … WebOct 2, 2013 · I encountered a problem on the SPI interface between ADE7753 and STM32 MCU. I configured my MCU as the master device, while ADE7753 is the slave. When I checked the signals particularly CS, SCLK, and MOSI on my MCU using an oscilloscope, everything is okay except that the MISO pin does not receive any response signal from …

WebThe clock phase determines the phase at which the data latching occurs at each bit transfer whether it’s the leading edge or the trailing edge. The clock polarity determines the IDLE state of the clock line whether it’s a HIGH or LOW. Having 2 possible states for each of the CPOL and CPHA gives us a total of 4 possible modes for the SPI clock.
