7.10 PROGRAMMING THE ISD 5216
When reading or writing a byte of data on the I
mechanisms for flow control are used, the first is the standard ACK
that the slave or master sends after reading or writing a byte, but the
ISD5216 also uses flow control by holding the clock line (SCL) low
until the chip is ready to transmit data,
For example, the sequence of sending the slave address will be as
follows:
This sequence prepares the
waits for the Tpud time before sending the next command sequence.
The read status command is a read request from the Host processor to the ISD5216 without
delivering a Command Byte. The Host supplies all of the clocks (SCL). The ISD5216 drives the data
line (SDA). During the read commands, to read status, send the following sequence.
Note: The processor could have sent an I
Address bytes
1. Send one byte 10000000 {Slave Address, R/W = 0} 80h.
2. Slave ACK.
3. Next time the clock is pulled high by the master, wait for SCL
1. Send I
2. Send one byte 10000000 {Slave Address, R/W = 0} 80h.
3. Send one byte 10000000 {Command Byte = Power Up} 80h.
4. Send I
1. Host executes I
2. Send Slave Address with R/W bit = “1” (Read) 81h.
3. Read one byte of data and send ACK, the read data is the status byte
4. Read one byte of data and send ACK, the read data is the upper address byte
5. Read one byte of data and send NACK, the read data is the lower address byte
