If LPI2C can run in low power consumption (such as stop mode) (Doze mode is turned on), how can I know that LPI2C runs in stop mode? The program should stop at the position where it enters STOP?

Hi @QJ_HAPPY,

In the RM rev.14 (Table 39-4 Module operation in available power modes), you can see that LPI2C is fully-functional in STOP2, and it supports Async operations in STOP1 and VLPS.

Fully-functional means that LPI2C can send the commands in the TX FIFO and receive data.

Table 52-10 & Table 52-11 list wakeup interrupts.

 

BR, Daniel
