Using Stm32l476 controller. Master is running at 30 MHz and slave
is running 15 MHz. In SPI master clock should be system clock/2 slave
clock should be system clock/4
Question 1: My understanding is slave need clock from master. Data
shifting completely depends on masters clock. In that case why
datasheet mentions slave clock selection condition?
Question 2: Which is max clock speed I can choose in the above
scenario?
Question 3: What if Master clock is 32 MHz ?How to choos
