Part Number: TCAN1146-Q1
Hi, team:
The following figure is from the TCAN1146 data manual :
Chapter 8.9 --- Switching Characteristics --- SPI SWITCHING CHARACTERISTICS
It is mentioned that the maximum clock frequency of SPI in sleep mode is 10 kHz.
My SPI master clock frequency is set to 2MHz, after TCAN1146 enters sleep mode, SPI master can still read/write TCAN1146 registers correctly without the need to configure SPI master clock frequency to 10KHz.
How to understand and test the 10 kHz SPI clock frequency in sleep mode?
Thanks for your suggestion.
BR,
