9 / 13 page Circuit Description (Continued) line during the 9th clock pulse, signifying an acknowledge. The LM27966 generates an acknowledge after each byte has been received. After the START condition, the I 2C master sends a chip address. This address is seven bits long followed by an eighth bit which is a data direction bit (R/W). The LM27966 address is 36h. For the eighth bit, a “0” indicates a WRITE and a “1” indicates a READ. The second byte selects the register to which the data will be written. The third byte contains data to write to the selected register. I 2C COMPATIBLE CHIP ADDRESS The chip address for LM27966 is 0110110, or 36h. INTERNAL REGISTERS OF LM27966 Register Internal Hex Address Power On Value General Purpose Register 10h 0010 0000 Main Display Brightness Control Register A0h 1110 0000 Auxiliary LED Brightness Control Register C0h 1111 1100 Note: EN-MAIN: Enables Dx LED drivers (Main Display) T0: Must be set to ’0’ EN-AUX: Enables DAUX LED driver (Indicator Lighting) EN-D5: Enables D5 LED voltage sense T1: Must be set to ’0’ Note: Dx4-Dx0: Sets Brightness for Dx pins (Main Display). 11111=Fullscale 20190112 FIGURE 3. Write Cycle w = write (SDIO = "0") r = read (SDIO = "1") ack = acknowledge (SDIO pulled down by either master or slave) rs = repeated start id = chip address, 36h for LM27966 20190109 FIGURE 4.
