Acknowledge
After a successful data transfer, each receiving
device is required to generate an acknowledge. The
acknowledging device pulls down the SDA line
during the ninth clock cycle, signaling that it received
the 8 bits of data.
The CAT1161/2 responds with an acknowledge after
receiving a START condition and its slave address.
If the device has been selected along with a write
operation, it responds with an acknowledge after
receiving each 8-bit byte.
When the CAT1161/2 begins a READ mode it
transmits 8 bits of data, releases the SDA line and
monitors the line for an acknowledge. Once it
receives this acknowledge, the CAT1161/2 will
continue to transmit data. If no acknowledge is sent
by
the
Master,
the
device
terminates
data
transmission and waits for a STOP condition.
WRITE OPERATIONS
Byte Write
In the Byte Write mode, the Master device sends the
START condition and the slave address information
(with the R/W
bit set to zero) to the Slave device.
After the Slave generates an acknowledge, the
Master sends a 8-bit address that is to be written
into the address pointers of the CAT1161/2. After
receiving another acknowledge from the Slave, the
Master device transmits the data to be written into the
addressed memory location. The CAT1161/2 acknow–
ledges once more and the Master generates the STOP
condition. At this time, the device begins an internal
programming cycle to non-volatile memory. While the
cycle is in progress, the device will not respond to any
request from the Master device.
Page Write
The CAT1161/2 writes up to 16 bytes of data in a single
write cycle, using the Page Write operation. The page
write operation is initiated in the same manner as the
byte write operation, however instead of terminating
after the initial byte is transmitted, the Master is allowed
to send up to 15 additional bytes. After each byte has
been transmitted, the CAT1161/2 will respond with an
acknowledge and internally increment the lower order
address bits by one. The high order bits remain
unchanged.
If the Master transmits more than 16 bytes before
sending the STOP condition, the address counter
‘wraps around,’ and previously transmitted data will be
overwritten.
When all 16 bytes are received, and the STOP
condition has been sent by the Master, the internal
programming cycle begins. At this point, all received
data is written to the CAT1161/2 in a single write cycle.
