Page Write
The CAT1021/22/23 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
CAT1021/22/23 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 CAT1021/22/23 in a single write cycle.
