10 FICR - Factory Information

Configuration Registers

The Factory Information Configuration Registers (FICR) are stored in the OTP memory.

FICR has two regions:

• A factory-programmed region that contains device information and has the INFO group registers.

• A customer-programmable region that contains empty registers for the customer to write data to. It

has the QSPI, MAC, and CALIB group registers.

Access to the customer-programmable region is controlled using the PROTECTION register.

The PROTECTION scenarios are:

• When PROTECTION is unprogrammed, neither read not write is enabled.

• When PROTECTION is programmed to 0x50FA50FA, full read and write access is enabled.

• When PROTECTION is programmed to 0x00000000, access protection is applied and readout of

QSPI.KEY is prevented.

The following table shows the access protection for the different register groups.
