READ SEQUENCE
Read sequences are comprised of two I2C compatible trans-
fer sequences: The first is a write sequence that only transfers
the two byte address to be accessed. The second is a read
sequence that starts at the address transferred in the previous
address only write access and increments to the next address
upon every data byte read. This is shown in Figure 18. The
write sequence consists of the Start Pulse, the Slave Device
Write Address (0xBA), and the Acknowledge bit; the next byte
is the least significant byte of the address to be accessed,
followed by its Acknowledge bit. This is then followed by a
byte containing the most significant address byte, followed by
its Acknowledge bit. Then a Stop bit indicates the end of the
address only write access. Next the read data access will be
performed beginning with the Start Pulse, the Slave Device
Read Address (0xBB), and the Acknowledge bit. The next 8
bits will be the read data driven out by the LM1276 preamp
associated with the address indicated by the two address
bytes. Subsequent read data bytes will correspond to the next
increment address locations. Data should only be read from
the LM1276 when both OSD windows and the Fade In/ Fade
Out are disabled.
