5.35. SPI Control Interface
The control interface to the Si3050 is a 4-wire interface modeled on commonly available micro-controller and serial
peripheral devices. The interface consists of four pins: clock (SCLK), chip select (CS), serial data input (SDI), and
serial data output (SDO). In addition, the Si3050 includes a serial data through output pin (SDITHRU) to support
daisy chain operation of up to 16 devices. The device can operate with 8-bit and 16-bit SPI controllers. Each SPI
operation consists of a control byte, an address byte (of which only the six LSBs are used internally), and either
one or two data bytes depending on the width of the controller. Bytes are transmitted MSB first.
There are a number of variations of usage on this four-wire interface as follows:
Continuous clocking. During continuous clocking, assertion of the CS pin controls the data transfers. The CS
pin must be asserted before the falling edge of SCLK on which the first bit of data is expected during a read
cycle, and must remain low for the duration of the 8-bit transfer (command/address or data), going high after the
last rising edge of SCLK after the transfer.
Clock only during transfer. The clock is active during the actual byte transfers only. Each byte transfer consists
of eight clock cycles in a return to 1 format.
SDI/SDO wired operation. Independent of the clocking options described, the SDI and SDO pins can be treated
as two separate lines or wired together if the master can tri-state its output during the data byte transfer of a
read operation.
The SPI state machine resets when the CS pin is asserted during an operation on an SCLK cycle that is not a
multiple of eight. This provides a mechanism for the controller to force the state machine to a known state in the
case where the controller and the device are not synchronized.
The control byte has the following structure and is presented on the SDI pin MSB first.
The bits are defined as follows:
7
6
54
3
2
10
BRCT
R/W
1
0
CID[0]
CID[1]
CID[2]
CID[3]
7BRCT
Indicates a broadcast operation that is intended for all devices in the daisy chain. This is only
valid for write operations as it causes contention on the SDO pin during a read.
6R/W
Read/Write Bit.
1 = Read operation.
0 = Write operation.
5
1
This bit must be 1 at all times.
4
0
This bit must be 0 at all times.
3:0
CID[0:3]
This field indicates the channel that is targeted by the operation. The 4-bit channel value is pro-
vided LSB first. The devices reside on the daisy chain such that device 0 is nearest to the con-
troller and device 15 is furthest away in the SDI/SDITHRU chain. See Figure 36.
As the CID information propagates down the daisy chain, each channel decrements the CID by
1. The device that receives a value of 0 in the CID field responds to the SPI transaction. See
Figure 37. If a broadcast to all devices connected to the chain is requested, the CID do not
decrement. In this case, the same 8- or 16-bit data is presented to all channels regardless of
the CID values.
