C.1 Serializer Overview
Appendix C
Programming the
Serializer
This appendix explains how to program the Serializer module and shows
the signal waveforms corresponding to Serializer 2- and 3-wire operation.
It contains the following sections:
This chapter provides complete information on how to use the L64724
registers for Serializer operation, but does not provide information on
how to program the registers for a specific application for the bits, which
depends on the addressed slave device.
The Serializer implements a write-only interface for serial 2- or 3-wire
compliant devices. A microprocessor or microcontroller writes to the
Group 4 Address Pointer Registers (APR) 59–62 to control Serializer
operation.
In the case of a 2-wire compliant slave, the serializer may be used to
perform writes to the slave as follows:

Section C.2, “Serializer Interface Signals and Configuration
Registers”
Section C.3, “Programming for Serial Mode (2-Wire Compliant)”
Section C.4, “Programming for 3-Wire Mode”
Write to APR 59 (TXSD)—generates the START condition
Write to APR 60 (STXD)—generates subsequent data
Note:
APR 62 needs the applicable bits (Serial_A, Serial_B, and
Serial_C) programmed before writing to APR 59–61.
