WebDec 6, 2024 · Suppose you do a memory read by calling HAL_I2C_Mem_Read_IT(). That sets the state to HAL_I2C_STATE_BUSY_RX. The SB and ADDR interrupts get handled properly, so that the next expected interrupt is TXE after the read address is sent. But if handling of that TXE gets held off, then both BTF and TXE will be set.
