Read operations are initiated the same way as write operations with the
exception that the Read/Write select bit in the device address byte must be set to a logic
‘1’. There are multiple read operations supported by the device:
- Current Address Read
- Random Address Read
- Sequential Read
Note: The
AT24CSW04X/AT24CSW08X contains a single Address Pointer register which is shared by both
the EEPROM and the Security register. As such, when changing from one region to the
other, the first read operation in the new region should begin with a dummy write
sequence (i.e. a random read operation with the new region’s device address and word
address bytes) in order to ensure the Address Pointer is set to a known value. See
Read Operations in the Security Register for additional requirements on read operations in the
Security register.
