73 / 95 page  73/95 ST7FLCD1 Display Data Channel Interfaces (DDC) Bits [7:0] = D[7:0] 8-bit Data Register. These bits contain the byte to be received or transmitted on the bus. Transmitter mode: Bytes are automatically transmitted when the software writes to the DR register. Receiver mode: The first data byte is automatically received in the DR register using the least significant bit of the address. Then, the next data bytes are received one by one after reading the DR register. DDC OWN ADDRESS REGISTER 1 (DDCOAR1) Read / Write Reset Value: 0000 0000 (00h) Bits [7:1] = ADD[7:1] Interface address. These bits define the I²C bus programmable address of the interface. They are not cleared when the interface is disabled (PE = 0). Bit 0 = Reserved. Forced to 0 by hardware. DDC OWN ADDRESS REGISTER 2 (DDCOAR2) Read / Write Reset Value: 0000 0000 (00h) Bits [7:1] = ADD[7:1] Interface address. These bits define the I²C bus programmable address of the interface. They are not cleared when the interface is disabled (PE = 0). Bit 0 = Reserved. Forced to 0 by hardware. DDC2B CONTROL REGISTER (DDCDCR) Read / Write Reset Value: 0000 0000 (00h) Bits [7:6] = Reserved. Forced by hardware to 0. Bit 5 = ENDCF End of Communication interrupt Flag. This bit is set by hardware. An interrupt is generated if ENDCE = 1. It must be cleared by software. 0 NACK or STOP condition not met in Read mode. 76 54 321 0 ADD7 ADD6 ADD5 ADD4 ADD3 ADD2 ADD1 0 76 54 321 0 ADD7 ADD6 ADD5 ADD4 ADD3 ADD2 ADD1 0 76 54 321 0 0 0 ENDCF ENDCE EDF EDE WP DDC2BPE |
