a-Si TFT LCD Single Chip Driver 240RGBx320 Resolution and 262K color ILI9341 7.1.3. Write Cycle Sequence The WRX signal is driven from high to low and then be pulled back to high during the write cycle. The host processor provides information during the write cycle when the display module captures the information from host processor on the rising edge of WRX. When the D/CX signal is driven to low level, then input data on the interface is interpreted as command information.

PAGE 35
a-Si TFT LCD Single Chip Driver 240RGBx320 Resolution and 262K color ILI9341 Host processor drives the CSX pin to low and starts by setting the D/CX bit on SDA. The bit is read by ILI9341 on the first rising edge of SCL signal. On the next falling edge of SCL, the MSB data bit (D7) is set on SDA by the host. On the next falling edge of SCL, the next bit (D6) is set on SDA. If the optional D/CX signal is used, a byte is eight read cycle width.

a-Si TFT LCD Single Chip Driver 240RGBx320 Resolution and 262K color ILI9341 7.1.10. Read Cycle Sequence The read mode of interface means that the host reads register’s parameter or display data from ILI9341. The host has to send a command (Read ID or register command) and then the following byte is transmitted in the opposite direction. ILI9341 latches the SDA (input data) at the rising edges of SCL (serial clock), and then shifts SDA (output data) at falling edges of SCL (serial clock).

a-Si TFT LCD Single Chip Driver 240RGBx320 Resolution and 262K color ILI9341 7.3. VSYNC Interface ILI9341 supports the VSYNC interface in synchronization with the frame-synchronizing signal VSYNC to display the moving picture with the 8080- Ⅰ/8080-Ⅱ system interface. When the VSYNC interface is selected to display a moving picture, the minimum GRAM update speed is limited and the VSYNC interface is enabled by setting DM[1:0] = “10” and RM = “0”.
PAGE 53
a-Si TFT LCD Single Chip Driver 240RGBx320 Resolution and 262K color ILI9341 The VSYNC interface has the minimum speed limitation of writing data to the internal GRAM via the system interface, which are calculated from the following formula. Internal clock frequency (fosc.) [Hz] = FrameFrequency x (DisplayLine (NL) + FrontPorch (VFP) + BackPorch (VBP)) x ClockCyclePerLines (RTN) x FrequencyFluctuation.
PAGE 54
a-Si TFT LCD Single Chip Driver 240RGBx320 Resolution and 262K color ILI9341 When calculate the internal clock frequency, the oscillator variation is needed to be taken into consideration. In the above example, the calculated internal clock frequency with ±10% margin variation is considered and ensures to complete the display operation within one VSYNC cycle. The causes of frequency variation come from fabrication process of LSI, room temperature, external resistors and VCI voltage variation.
