CAT140xx
transmitted the CAT140xx will respond with an
acknowledge and internally increments the four low order
address bits. The high order bits that define the page address
remain unchanged. If the Master transmits more than sixteen
bytes prior to sending the STOP condition, the address
counter ‘wraps around’ to the beginning of page and
previously transmitted data will be overwritten. Once all
sixteen bytes are received and the STOP condition has been
sent by the Master, the internal Write cycle begins. At this
point all received data is written to the CAT140xx in a single
write cycle.
Acknowledge Polling
The acknowledge (ACK) polling routine can be used to
take advantage of the typical write cycle time. Once the stop
condition is issued to indicate the end of the host’s write
operation, the CAT140xx initiates the internal write cycle.
The ACK polling can be initiated immediately. This
involves issuing the start condition followed by the slave
address for a write operation. If the CAT140xx is still busy
with the write operation, NoACK will be returned. If the
CAT140xx has completed the internal write operation, an
ACK will be returned and the host can then proceed with the
next read or write operation.
