TFDU8108
Vishay Semiconductors
The bits shown are placed on the TX (DATA) line and
clocked into the transceiver using the rising edge of
the SCLK signal. Only the data bits are shown as it is
assumed that a clock is always present, and that the
transceiver samples the data on the rising edge of
each clock pulse.
Note:
as illustrated in the diagram above, the protocol
uses "Little Endian" ordering of bits, so that the LSB is
sent first, and the MSB is sent last for register
addresses, transceiver addresses, and read/write
data bytes. The notation that follows presents all
addresses and data in LSB-to-MSB order (bits 0, 1, 2,
3, ... 7) unless otherwise stated.
One-byte Special Commands
One-byte special commands are used for time-critical
transceiver commands, such as full transceiver reset.
A total of six special commands are possible,
although only one command is available on the
TFDU8108 and TFDU6108.
Two-byte Write Commands
Two-byte write commands are used for setting the
contents of transceiver registers which control trans-
ceiver such as shutdown/enable, receiver mode, LED
power level, etc.
The register space requires four register address bits
(R0-3), although three codes are used for controlling
transceiver (see above), and the 1111 escape code is
for extended commands. The 3-bit transceiver
address (A0-3) is for selecting the destination, e.g.
010 to TFDU8108 and 001 to TFDU6108.
The second byte is data field (D0-7) for setting the
characteristics of the transceiver module, e.g. SIR
mode (00) or VFIR (05) when the register address is
0001.
The basic two-byte write command is illustrated
