Appendix A
Programming the
L64704 Using the Serial
Bus Protocol
This appendix discusses how to program the L64704 internal registers
and data tables in Serial Host Interface mode. This chapter is intended
primarily for system programmers who are developing software drivers
using the serial bus.
This chapter contains the following sections:
The multi-master serial bus interface has two one-bit lines – SDATA
(Serial Data) and D[0] (Serial Clock) – that are connected to the bus as
shown in
at a logic “1” value when the bus is not in operation.
Section A.1, “Serial Bus Protocol Overview,”
overview of the serial bus protocol.
Section A.2, “Programming the Slave Address Using the Serial Bus
Interface,”
Section A.3, “Write Cycle Using the Serial Bus Interface,”
example of a serial bus write cycle.
Section A.4, “Read Cycle Using the Serial Bus Interface,”
example of a serial bus read cycle.
