Rev. 1.8 ︱ Page 14 CM6317A USB Audio Single Chip Solution for Stereo Microphone & Line In 7.1.2 Slave Mode: “7-bit slave address = 7‟b0111000” On the MCU serial interface, the CM6317A can serve as a slave device with bit rates up to 400Kbps (in fast mode). The MCU can write data to the CM6317A or read data from the CM6317A (No size limitations when using the I2C Interface). Since the host side and MCU can both access to the internal registers, access contention- when both host and MCU try to access the same register- should be avoided by the application. The 7-bit slave address of the CM6317A is assigned as 7‟b0111000. When data is written by the MCU, the CM6317A will NOT transfer any interrupt to the PC until the INT bit of the I2C control Register has been set by the MCU. The USB host will keep polling the upward HID report every 1ms. When any button is pressed or released, or MCU data is incoming, the CM6317A will transfer 16 bytes of HID report to the USB host. In I2C Slave Mode, the CM6317A has one open-drain input pin „SCLK‟ where it receives the serial clock from the MCU, and one open-drain I/O pin „SDAT‟ where it sends or receives serial signals to/from the MCU. As shown below, „SDAT‟ should be stable when „SCLK‟ is high, and can transition only when „SCLK‟ is low. START and STOP conditions shown below are the exception. Every transaction begins from a START, and ends with a STOP, or another START (repeated START). www.cmedia.com.tw Copyright © C-Media Electronics Inc. Rev. 1.8 ︱ Page 15 CM6317A USB Audio Single Chip Solution for Stereo Microphone & Line In The figure below demonstrates a typical transaction. After every 8 bits sent by the transmitter, the receiver should send one bit low for positive acknowledgement or one bit high for negative acknowledgement. After the negative acknowledgement, a STOP or repeated START should follow. The next figure shows more details about the acknowledgement bit. Note that „SCLK‟ is always driven by the master. P SDAT MSB Acknowledgement Signal from Receiver Acknowledgment Signal from Receiver SCLK S or Sr 1 2 7 8 9 1 2 ACK START or Repeated START Condition 3-8 9 ACK Sr Sr or P STOP or Repeated START Condition Data Transfer on the MCU Interface The figure below shows a complete data transfer. After a START, the MCU should send 7-bit slave address (7‟b0111000) first, and then the 8th bit denotes a read transfer when it‟s high; or a write transfer when it‟s low. The first acknowledgement always comes from the CM6317A. www.cmedia.com.tw Copyright © C-Media Electronics Inc. Rev. 1.8 ︱ Page 16 CM6317A USB Audio Single Chip Solution for Stereo Microphone & Line In In the write transfer, the MCU continues to act as the master and the transfer direction is not changed. The following figure gives an example of a write transfer. MCU write: S 0x70 0 addr 0 Byte 0 0 Byte 1 0 From CM6317A to MCU …. 0 Byte N P From MCU to CM6317A S START condition P STOP condition 0 Positive acknowledge 1 Negative acknowledge Byte N 0 One byte data 0x70 is the slave address of CM6317A, and it also tells CM6317A that it‟s receiving a write command. CM6317A regards the first coming DATA byte as the register address. The second DATA byte is the DATA content that MCU writes at the register address. CM6317A will auto-increment the register address to the next register address for the following writes DATA. The figure below shows an example of read transfer. The MCU read command can not set the register address, so the MCU may use a write command to set the register address first and then start the read command. Because the CM6317A auto-increments the register address, the second DATA byte will be the register data on the next address. MCU read: S 0x70 0 addr 0 S 0x71 0 Byte 0 0 Byte 1 0 ….. 0 From CM6317A to MCU Byte N 1 P From MCU to CM6317A S START condition P STOP condition 0 Positive acknowledge 1 Negative acknowledge Byte n One byte data The figure below gives a complete picture of a typical transaction between the MCU and CM6317A. After a START, the MCU should send a 7-bit slave address (7‟b0111000) first, and then the 8th bit denotes a read transfer when it‟s high; or a write transfer when it‟s low. www.cmedia.com.tw Copyright © C-Media Electronics Inc. Rev. 1.8 ︱ Page 17 CM6317A USB Audio Single Chip Solution for Stereo Microphone & Line In MCU write: S 0x70 0 addr 0 Byte 0 0 Byte 1 0 ….. 0 Byte N Byte 1 0 ….. 0 Byte N 1 P 0 P MCU read: S 0x70 0 addr 0 S 0x71 0 Byte 0 0 From CM6317A to MCU From MCU to CM6317A S START condition P STOP condition 0 Positive acknowledge 1 Negative acknowledge Byte N One byte data During a write transfer, the MCU continues acting as the transmitter. The CM6317A regards the first DATA byte as the start register address. The following DATA bytes are the content of the registers that the MCU requests. In a read transfer, two transactions are necessary. The MCU resets the start register address by the first transaction, then direction changes to get N of data. www.cmedia.com.tw Copyright © C-Media Electronics Inc.
