11 / 30 page 點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC. DM164 8x3-CHANNEL CONSTANT CURRENT LED DRIVERS Version:A.002 Page 10 Serial Data Interface The DM164 includes a flexible data transfer interface. The data can be transferred from DIN pin to the shift registers at either the rising edge of DCK or the falling edge of DCK depending on the signal DCKPH. After all data are clocked in, a high level LTH signal can transfer the serial data to the data latches (Level Sensitive). The serial data format can be 192-bit or 384-bit wide, depending on the operating mode of the device. Operating Modes The DM164 has two operating modes depending on the signal MSEL. Table 1 shows the available operating modes. When MSEL = H, the device operates at the D&G mode. D&G mode is used to set dot correction data and global brightness control data after IC power up or any time. When MSEL = L, the device becomes GD mode. GD mode is used to set grayscale PWM data after D&G mode. Table 1. Two Operating Modes MSEL MODE SHIFT REGISTER H Dot Correction Data & Global Brightness Control Data Input Mode (D&G mode) 192-bit L Grayscale PWM Data Input Mode (GD mode) 384-bit D&G Mode Data Format At D&G mode, dot correction data of all channels and global brightness control data of different colors are transferred into the chip at the same time. The complete dot correction data format consists of 24 x 7-bit and the global brightness control data of three different colors consists of 3 x 8-bit. The total shift registers width at D&G mode is 192-bit. All data is clocked in with MSB first. Figure 1 shows the D&G mode data format.

D&G Mode Data Format (D&G[191:0]) To operate the DM164 in D&G mode, MSEL must be set to high. The shift register width is then set to 192-bit wide. The input data can be transferred at either the rising edge of DCK |
