AD5933
READ OPERATIONS
The AD5933 uses two I
block read.
Receive Byte
In the AD5933, the receive byte protocol is used to read a single
byte of data from a register address whose address has previously
been set by setting the address pointer.
In this operation, the master device receives a single byte from a
slave device as follows (see Figure 39):

6.
The master device asserts a start condition on SDA.
The master sends the 7-bit slave address followed by the
read bit (high).
The addressed slave device asserts an acknowledge on SDA.
The master receives a data byte.
The master asserts a no acknowledge on SDA (the slave
needs to check that master has received data).
The master asserts a stop condition on SDA and the
transaction ends.

Block Read
In this operation, the master device reads a block of data from a
slave device (see Figure 40). The start address for a block read
must previously have been set by setting the address pointer.

The master device asserts a start condition on SDA.
The master sends the 7-bit slave address followed by the
write bit (low).
The addressed slave device asserts an acknowledge on SDA.
The master sends a command code (1010 0001) that tells
the slave device to expect a block read.
The slave asserts an acknowledge on SDA.
The master sends a byte-count data byte that tells the slave
how many data bytes to expect.
The slave asserts an acknowledge on SDA.
The master asserts a repeat start condition on SDA. This is
required to set the read bit high.
