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 a logic
‘1’. There are four read operations:
- Current Address Read
- Random Address Read
- Sequential Read
- Serial Number Read
Note: The
AT24CS32
contains a single Address Pointer register, which is shared by both the EEPROM and the
serial number. 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
Serial Number Read
for additional requirements on the serial number read.
