DM11H Serial Data Interface DM11H includes a flexible data transfer interface. The data can be transferred from DAI pin to the shift registers at the rising edge of CLK. After all data are clocked in, a rising edge of the LAT signal can transfer the serial data to the data latches (Edge trigger). The serial data format can be 8-bit or 10-bit wide, depending on the operating mode of the device. Operation Mode DM11H has two operating modes depending on the combination of CLK and LAT signals. The table below shows the available operating modes. For normal operation (SD mode), the data width of shift register is 8-bit, which is used to set 8 bits serial-in image data. The sequence of the combination of CLK and LAT explains in following pages is used to change the operation mode. If there are four triggering clock pulses (CLK) with high level latch (LAT ), DM11H will change to command data input mode (CD mode) at falling edge of the latch pulse (LAT ) then user can make ten triggering clock pulses to set 7-bit GBC data (default value after power-on is 7’b1000000), 2-bit voltage level selection of short detection (default value after power-on is 1’b10) and 1-bit sleep control data (default value is 1’b0) OPERATION MODE SHIFT REGISTER Serial-in Data Input Mode (SD mode) 8-bit Command Data Input Mode (CD mode) 10-bit |
