Hi,
Yes, the chip level stop is entered once WFI instruction is executed.
“If FlexCAN receives the global Stop mode request during Freeze mode, it sets the LPMACK bit, negates the FRZACK bit and then sends the Stop Acknowledge signal to the CPU, in order to shut down the clocks globally.” (Section 53.5.11.3 RM rev.9). Please see Section 25.2.2.6 Stop mode acknowledge error.

Daniel
