14.1.4.
Data transmission read format of the RV5C386A
The RV5C386A allows the following three readout method of data an internal register.
1) The first method to reading data from the internal register is to specify an internal address by setting the
internal address pointer and the transmission format register described 14.1.3, generate the Repeated
Start Condition (See section 14.1.2-(3)) to change the data transmission direction to perform reading.
The internal address pointer is set to Fh when the Stop Condition is met. Therefore, this method of
reading allows no insertion of Stop Condition before the Repeated Start Condition. Set 0h to the
Transmission Format Register when this method used.
