Page Write
The CAT1640/41 writes up to 64 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 additional 63 bytes. After each byte has been
transmitted, the CAT1640/41 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 64 bytes before sending
the STOP condition, the address counter
wraps around,
and previously transmitted data will be overwritten.
When all 64 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 CAT1640/41 in a single write cycle.
