SMBus Protocols DATA S ADDRESS WR ACK 7 Bits COMMAND DATA P 8 Bits ACK ACK S ADDRESS WR ACK 7 Bits COMMAND RD NACK 8 Bits S ADDRESS 7 Bits ACK ACK 8 Bits P S ADDRESS WR ACK 7 Bits COMMAND 8 Bits P ACK DATA RD NACK S ADDRESS 7 Bits ACK 8 Bits P Slave Address Command Byte: selects Data Byte: data goes which register you writing to. into the register set by the command byte. Slave Address Command Byte: selects which register you reading from. Slave Address: repeated due to change in data– flow direction. Data Byte: reads from the register set by the command byte. Command Byte: sends command with no data, usually used for one–shot Data Byte: reads data from the register commanded by the last Read Byte. command. S = Start Condition P = Stop Condition Shaded = Slave Transmission Write Byte Format Read Byte Format Send Byte Format Receive Byte Format 8 Bits Acknowledge (ACK) Acknowledge (ACK) provides a positive handshake between the host and the MC1066. The host releases SDA after transmitting eight bits, then generates a ninth clock cycle to allow the MC1066 to pull the SDA line Low to acknowledge that it successfully received the previous eight bits of data or address. Data Byte After a successful ACK of the address byte, the host must transmit the data byte to be written or clock out the data to be read. (See the appropriate timing diagrams.) ACK will be generated after a successful write of a data byte into the MC1066. Stop Condition (STOP) Communications must be terminated by a stop condition (a Low to High transition of SDA while SCL is High). The Stop Condition must be communicated by the transmitter to the MC1066. (See SMBus Write/Read Timing Diagram.) Command Byte Description Command Code Function RIT 00h Read Internal Temp (INT_TEMP) RET 01h Read External Temp (EXT_TEMP) RS 02h Read Status Byte (STATUS) RC 03h Read Configuration Byte (CONFIG) RCR 04h Read Conversion Rate Byte (CONV_RATE) RIHL 05h Read Internal High Limit (INT_HLIM) RILL 06h Read Internal Low Limit (INT_LLIM) REHL 07h Read External High Limit (EXT_HLIM) RELL 08h Read External Low Limit (EXT_LLIM) WC 09h Write Configuration Byte (CONFIG) WCR 0Ah Write Conversion Rate Byt3 (CONV_RATE) WIHL 0Bh Write Internal High Limit (INT_HLIM) WILL 0Ch Write Internal Low Limit (INT_LLIM) WEHL 0Dh Write External High Limit (EXT_HLIM) WELL 0Eh Write External Low Limit (EXT_LLIM) OSHT 0Fh One Shot Temp Measurement RMID FEh Read Manufacturer ID (MFR_ID) RMREV FFh Read Manufacturer Revision Number (MFR_REV) NOTE: Proper device operation is NOT guaranteed if undefined locations (10h to FDh) are addressed. In case of erroneous SMBus operation (RECEIVE_BYTE command issued immediately after WRITE_BYTE command) the MC1066 will ACKnowledge the address and return 1111 1111b to signify an error. Under no condition will it implement an SMBus “timeout.” |
