4 / 9 page EADOG XL160-7 Page 4 ELECTRONIC ASSEMBLY reserves the right to change specifications without prior notice. Printing and typographical errors reserved. 4 WIRE, 8-BIT SPI-MODE Pin CS0 is used for chip select and bus cycle reset. Pin CD is used to determine the content of the data been transferred. During each write cycle, 8 bits of data, MSB first, are latched on eight rising SCK edges into an 8-bit data holder. If CD=0, the data byte will be decoded as command. If CD=1, this 8-bit will be treated as data and transferred to proper address in the Display Data RAM on the rising edge of the last SCK pulse. Pin CD is examined when SCK is pulled low for the LSB (D0) of each token.The toggle of CS0 for each byte of data/command is recommended but optional. The clock-pulse rate of the SCK line can be up to 8 MHz. 3 WIRE, 8-BIT SPI-MODE The data format is identical to 4-wire, 8-bit SPI-mode. However in addition to CS0 pin, CD pin transitions will also reset the bus cycle in this mode. If CS0 is hardwired to enable the display, the bus can work properly with only three signal pins. The clock-pulse rate of the SCK line can be up to 8 MHz. Serial Modes BM0 D6 Description 0 0 4-wire, 8-Bit SPI 0 1 3 wire, 8-Bit SPI 1 0 3-wire, 9-Bit SPI 1 1 2-wire, I2C DATA TRANSFER The EA DOGXL160-7 supports four serial modes. The data transfer is unidirectional (exception I2C mode is bidrektional). That means that data can only be written; it cannot be read back. Compared to other displays, a busy query is not necessary. The clock-pulse rate of the SCL line can be up to 12 MHz at 3.3V, depending on the supply voltage and interface mode. You will find more detailed information on timing in chapter „AC CHARACTERISTICS“ of the data sheet of the UC1610 controller, which you will find on our website at http://www.lcd-module.de/eng/pdf/zubehoer/uc1610.pdf |
