Byte 0 indicates the address of the control register to be
written. The two most significant bits are set to 0, while the
six least significant bits contain the control register address.
Byte 1 is a don
’
t carebyte. This byte is included in the
protocol in order to maintain compatibility with current and
future Texas Instruments
’
digital audio products, including
the DIT4096 and DIT4192 digital audio transmitters. Byte 2
contains the 8-bit data for the control register addressed in
Byte 0.
As shown in Figure 8, a write sequence starts by bringing the
CS
input low. Bytes 0, 1, and 2 are then written to program
a single control register. Bringing the
CS
input high after the
third byte will write just one register. However, if
CS
remains
low after writing the first control byte, the port will auto-
increment the address by 1, allowing successive addresses

Set CS = 1 here to write one register or buffer location.
Keep CS = 0 to enable auto-increment mode.

after each byte is written as long as the
CS
input remains
low. This is referred to as auto-increment operation, and is
always enabled for the SPI port.
CONTROL REGISTER MAP (SRC4193 ONLY)
The control register map for the SRC4193 is shown in Table
4. Register 0 is reserved for factory use and defaults to all
zeros upon reset. The user should avoid writing this register,
as unexpected operation may result if Register 0 is pro-
grammed to an arbitrary value. Registers 1 through 5 contain
control bits, which are used to configure the internal functions
of the SRC4193. All other register addresses are reserved
and should not be used in customer applications.
