(5) Data transmission read format of the R2051
The R2051 allows the following three read out method of data an internal register.
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 P25 (4), generate the Repeated Start Condition (See
P24 (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.
