I am using SPI of TMS320F2837xS to communicate with CY15B102Q(FRAM) to store faults. Read/Write works fine but locking and unlocking memory array of FRAM using BP1 & BP0 is not consistent. Any one can help me to resolve the issue.
Note: WP pin Connected to 3.3V
Please let us know the sequence fo operations you are performing to lock and unlock memory array.
