This sequence (Figure 5) starts in the same way as the single READ from random loca-
tion (Figure 3). Instead of generating a no-acknowledge bit after the first byte of data has
been transferred, the master generates an acknowledge bit and continues to perform
byte READs until “L” bytes have been read.
This sequence (Figure 6) starts in the same way as the single READ from current location
(Figure 4 on page 11). Instead of generating a no-acknowledge bit after the first byte of
data has been transferred, the master generates an acknowledge bit and continues to
perform byte READs until “L” bytes have been read.
This sequence (Figure 7) begins with the master generating a start condition. The slave
address/data direction byte signals a WRITE and is followed by the HIGH then LOW
bytes of the register address that is to be written. The master follows this with the byte of
write data. The WRITE is terminated by the master generating a stop condition.
