416 / 712 page  11. Serial Communication Interface Rev.2.00 Mar. 22, 2007 Page 392 of 684 REJ09B0352-0200 SCK/port Data TE C/ A CKE1 CKE0 Bit 6 Bit 7 (2) TE=0 (3) C/ A=0 (1) End of transmission (4) Low-level output Half-cycle low-level output occurs Figure 11.23 Operation when Switching from SCK Pin Function to Port Pin Function 2. Usage Note The procedure shown below should be used to prevent low-level output when switching from the SCK pin function to the port function. As this procedure temporarily places the SCK pin in the input state, the SCK/port pin should be pulled up beforehand with an external circuit.With DDR = 1, DR = 1, C/ A = 1, CKE1 = 0, CKE0 = 0, and TE = 1, make the following settings in the order shown. (1) End of serial data transmission (2) TE bit = 0 (3) CKE1 bit = 1 (4) C/ A bit = 0 ... switchover to port output (5) CKE1 bit = 0 |
