Pin Description
CY2213 Two-Wire Serial Interface
Introduction
The CY2213 has a two-wire serial interface designed for data
transfer operations, and is used for programming the P and Q
values for frequency generation. S
clk
is the serial clock line
controlled by the master device. S
data
is a serial bidirectional
data line. The CY2213 is a slave device and can either read or
write information on the dataline upon request from the master
device.
Figure 1
shows the basic bus connections between master
and slave device. The buses are shared by a number of
devices and are pulled high by a pull-up resistor.
Serial Interface Specifications
Figure 2
shows the basic transmission specification. To begin
and end a transmission, the master device generates a start
signal (S) and a stop signal (P). Start (S) is defined as
switching the S
data
from HIGH to LOW while the S
clk
is at
HIGH. Similarly, stop (P) is defined as switching the S
data
from
LOW to HIGH while holding the S
clk
HIGH. Between these two
signals, data on S
data
is synchronous with the clock on the S
clk
.
Data is allowed to change only at LOW period of clock, and
must be stable at the HIGH period of clock. To acknowledge,
drive the S
data
LOW before the S
clk
rising edge and hold it
LOW until the S
clk
falling edge.
Serial Interface Format
Each slave carries an address. The data transfer is initiated by
a start signal (S). Each transfer segment is 1 byte in length.
The slave address and the read/write bit are first sent from the
master device after the start signal. The addressed slave
device must acknowledge (Ack) the master device. Depending
on the Read/Write bit, the master device will either write data
into (logic 0) or read data (logic 1) from the slave device. Each
time a byte of data is successfully transferred, the receiving
device must acknowledge. At the end of the transfer, the
master device will generate a stop signal (P).
Serial Interface Transfer Format
Figure 2
shows the serial interface transfer format used with
the CY2213. Two dummy bytes must be transferred before the
first data byte. The CY2213 has only three bytes of latches to
store information, and the third byte of data is reserved. Extra
data will be ignored.
