Data Sheet
Rev. B | Page 20 of 52
Figure 30 shows a typical multibyte read sequence for reading
internal registers. The cycle begins with a start condition, followed
by the 7-bit device address (0x34), followed by the R/W bit set
to 0 for a write cycle. The ADP5589 acknowledges the address
byte by pulling the data line low. The address of the register
from which data is to be read is sent next. The ADP5589 acknowl-
edges the register pointer byte by pulling the data line low. A start
condition is repeated, followed by the 7-bit device address (0x34),
followed by the R/W bit set to 1 for a read cycle. The ADP5589
acknowledges the address byte by pulling the data line low. The
8-bit data is then read. The address pointer is then incremented
to read the next data byte, and the host continues to pull the data
line low for each byte (master acknowledge) until the n data
byte is read. The host pulls the data line high (no acknowledge)
after the last byte is read, and a stop condition completes the
sequence.
