Receive Byte
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 can be used for consecutive
reads of the same register as shown below:

SMBus Addresses
The EMC1023 may be ordered with one of four 7-bit slave addresses as shown in Order Numbers.
Attempting to communicate with the EMC1023 SMBus interface with an invalid slave address or invalid
protocol results in no response from the device and does not affect its register contents. The EMC1023
supports stretching of the SMCLK signal by other devices on the SMBus but will not perform this
operation itself.
3.6
SMBus Timeout
The EMC1023 includes an SMBus timeout feature. Following a 25 ms period of inactivity on the
SMBus, the device will timeout and reset the SMBus interface.
