AWR6843AOP: Peripherals in low power operation (MSS clock to 40MHz)

Champs,

Here is question of peripherals of AWR6843(AOP) when running in low power idle mode.

From "Low Power Demo" of Industrial Toolbox, MSS can be clock down using xWR6843_mss_vclk_40M() function.

When MSS running at 40MHz clock, how to use peripherals of CAN, SPI, I2C, UART, QSP, and QSPI Flash?

From the user's guide of Low Power Demo, "CAN_FD and QSPI" can run on slower clock speed.

   [Q1] So, how about (classic) CAN and QSPI Flash?

   [Q2] If it is possible to use CAN, how to make it working? Is it required to change the configurations every time according to the MSS frequency of 40MHz and 200MHz?

Best regards,

Hayden
