140 / 355 page  2-52 38B5 Group User’s Manual APPLICATION 2.3 Serial I/O Control procedure: When the registers are set as shown in Figure 2.3.22, the serial I/O1 can transmit 1-byte data by writing data to the serial I/O1 register. Thus, after setting the CS signal to “L”, write the transmission data to the serial I/O1 register by each 1 byte; and return the CS signal to “H” when the target number of bytes has been transmitted. Figure 2.3.24 shows a control procedure. Fig. 2.3.24 Control procedure Initialization SC11 (address 001916) SC12 (address 001A16) SC13 (address 001C16) P6 (address 000C16), bit2 P6D (address 000D16), bit2 SC11 (address 001916), bit4 001000012 00XX00002 011XXXXX2 1 1 1 P6 (address 000C16), bit2 0 SIO1CON2 (address 001A16), bit5 ? 0 1 RESET SIO1 (address 001B16) All data have been transmitted ? Y P6 (address 000C16), bit2 1 N q X: This bit is not used here. Set it to “0” or “1” arbitrarily. Judgment of completion of transmitting 1-byte data Use any of RAM area as a counter for counting the number of transmitted bytes. Judgment of completion of transmitting the target number of bytes Returning CS signal output level to “H” when transmission of the target number of bytes is completed Serial I/O1 setting CS signal output level to “H” setting CS signal output port setting Enabled serial I/O1 CS signal output level to “L” setting Transmission data write (Start of 1-byte data transmission) Transmission data |
