SPIS Slave Bit rates

[james]

Hi,

  I have a question about bit rates of spis slave (Fspis).What is the minimum bit rates of spis slave? nRF52832 need to communicate with a mcu that it only can work on the max bit rates at 20Khz. So can nRF52832 spis work on 20Khz? The electrical specification of spis only refer the max bit rates.

There isn't a minimum - you could stop the clock, and it would just wait.
