108 / 368 page  External memory interface (EMI) RM0319 108/368 Doc ID 022640 Rev 3 EMI read without acknowledgement signal (EMI_WAIT#) Figure 29. EMI read (without ACK) This timing diagram indicates a typical EMI read cycle. Acknowledgement signal (EMI_WAIT#) is ignored in this case. It also indicates the registers which affect the timing duration of the different interface signals. EMI read with acknowledgement signal (EMI_WAIT#) Figure 30. EMI read (with ACK) This timing diagram indicates a typical EMI read cycle in which the Acknowledgement signal (EMI_WAIT#) is considered. It also indicates the registers which affect the timing duration of the different interface signals . 9.4 Programming examples Example 1: A 16-bit peripheral which does not use byte lane procedure is connected with EMI. The peripheral does not provide the acknowledgement signal. We want to perform read and write to it. The peripheral is connected to CS0.
