READ OPERATIONS
the block read.
Receive Byte
In the AD5934, 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 29):
1. The master device asserts a start condition on SDA.
2. The master sends the 7-bit slave address followed by the
read bit (high).
3. The addressed slave device asserts an acknowledge on SDA.
4. The master receives a data byte.
5. The master asserts a no acknowledge on SDA (the slave
needs to check that master has received data).
6. 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 30). The start address for a block read
must previously have been set by setting the address pointer.
1. The master device asserts a start condition on SDA.
2. The master sends the 7-bit slave address followed by the
write bit (low).
3. The addressed slave device asserts an acknowledge on SDA.
4. The master sends a command code (1010 0001) that tells
the slave device to expect a block read.
5. The slave asserts an acknowledge on SDA.
6. The master sends a byte-count data byte that tells the slave
how many data bytes to expect.
7. The slave asserts an acknowledge on SDA.
8. The master asserts a repeat start condition on SDA. This is
required to set the read bit high.
9. The master sends the 7-bit slave address followed by the
read bit (high).
10. The slave asserts an acknowledge on SDA.
11. The master receives the data bytes.
12. The master asserts an acknowledge on SDA after each
data byte.
13. A no acknowledge is generated after the last byte to signal
the end of the read.
14. The master asserts a stop condition on SDA to end the
transaction.
