The Read Byte protocol is used to read one byte of data from the registers as shown in
The Send Byte protocol is used to set the internal address register pointer to the correct address
location. No data is transferred during the Send Byte protocol as shown in
The Receive Byte protocol is used to read data from a register when the internal register address
pointer is known to be at the right location (e.g. set via Send Byte). This is used for consecutive reads
of the same register as shown in
The EMC1046/EMC1047-1 devices respond to the 7-bit slave address 1001_100xb.
The EMC1046-6 will respond to the 7-bit slave address 1001_101xb.
The EMC1047-2 will respond to the 7-bit slave address 1001_000xb.
Note: Other addresses are available. Contact SMSC for more information.
The EMC1046/EMC1047 support SMBus Timeout. If the clock line is held low for longer than 30ms,
the device will reset its SMBus protocol. This function can be enabled by setting the TIMEOUT bit in
the Consecutive Alert Register (see
