copy-protected pages or if the PF flag is set. This operation can be verified by reading the AA flag bit in the E/S

byte through the Read Scratchpad command.

6.5.4.4 Read Memory [F0h]

The host can read the FRAM memory by issuing the Read Memory command (F0h), followed by the 2-byte

address. If the host issues an address greater than 03D3h, the device sets the six most significant address

bits to zero. The host can then read the data from either the address within the address range or the modified

address until address 03D3h is reached. If the host continues to read further, the TMF0008 transmits 1s. The

host can terminate the Read Memory command sequence by issuing a reset pulse.

6.5.4.5 Extended Read Memory [A5h]

The Extended Read Memory command works similar to the Read Memory command except for the 2-byte CRC

that is transmitted at the end of each memory page. The host can read the FRAM memory by issuing the

Extended Read Memory command (A5h), followed by the 2-byte address. If the host issues an address greater

than 03D3h, the device sets the six most significant address bits to zero. The host can then read the data from

either the address within the address range or the modified address until the end of a 32-byte page. At the end

of the memory page, the host reads the 2-byte inverted CRC. If the host continues to read, the host receives

the data corresponding to the beginning of next page and so on until the end address 03D3h is reached. If the

host continues to read further, the TMF0008 transmits 1s. The host can terminate the Read Memory command

sequence by issuing a reset pulse.
