Acknowledge Polling
Disabling of the inputs 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 opration, the CAT1024/25 initiates the
internal write cycle. ACK polling can be initiated
immediately. This involves issuing the start condition
followed by the slave address for a write operation. If
the device is still busy with the write operation, no
ACK will be returned. If a write operation has
completed, an ACK will be returned and the host can
then proceed with the next read or write operation.
WRITE PROTECTION PIN (WP)
The Write Protection feature (CAT1025 only) allows
the user to protect against inadvertent memory array
programming. If the WP pin is tied to V
CC
, the entire
memory array is protected and becomes read only.
The CAT1025 will accept both slave and byte addre-
sses, but the memory location accessed is protected
from programming by the device’s failure to send an
acknowledge after the first byte of data is received.
READ OPERATIONS
The READ operation for the CAT1024/25 is initiated in the
same manner as the write operation with one exception,
the Rˉˉ bit is set to one. Three different READ operations
are possible: Immediate/Current Address READ,
Selective/Random READ and Sequential READ.
