This read operation is not limited to 3 bytes but can be extended until the register address pointer
reaches its maximum value.
78M6610+PSU Data Sheet
If the register address pointer has not been set by previous operations, it is necessary to set it issuing a
command as follows:
Random Read: random read operations allow the master to access any register in a random manner. To
perform this operation, the register address must be set as part of the write operation. After the address is
sent, the master generates a start condition following the acknowledge response. This sequence
completes the write operation. The master should issue the control byte again this time, with the R/W bit
set to 1 to indicate a read operation. The 78M6610+PSU will issue the acknowledge response, and
transmit the data.
At the end of the transaction the master will not acknowledge the transfer and generate a STOP
condition.
