HDM8515 Datasheet, PDF (47/75 Pages) Hynix Semiconductor – DVB/DSS Compliant Receiver

retransmit the HDM8515 slave address, this time with the read/not write bit set to one (read). This
will be acknowledged by the HDM8515, which then assumes the role of slave transmitter and
transmits the requested byte. This byte should be acknowledged by the master receiver. If no
stop condition is generated by the master, the HDM8515 will increment its word address pointer
and transmit the next byte of information. This process is detailed in Figure 25.
