Description

OTP_CONFIG_

PWD_EN

Defines if the write access with the WRITE CONFIG command is password

protected with the CFG_PWD password. Access to the configuration memory

always depends on related lock options:

0b ... Write access to the configuration memory is possible without password

authentication

1b ... Write access to the configuration memory is only possible with a valid

previous password authentication with the CF_PWD password

Note: If changes with the WRITE CONFIG command are required in the

application, program and activate the configuration memory password with the

OTP_CONFIG_PWD _EN after the IC initialization. In case no further changes

are required, use WRITE_CONFIG command to lock the write access to the

configuration memory with the OTP_CONFIG_ LOCK bit. See Table 28.

OTP_AFI_LOCK 1

Defines if the AFI in block 17 is write locked:

0b ... AFI is not write locked

1b ... AFI is write locked. The AFI can also be locked with the LOCK AFI

command (see Section 8.5.2.8)

Note: To avoid unauthorized change of the AFI, lock or password protect the AFI.

OTP_EAS_

LOCK

Defines if the current state of the EAS mode and the EAS ID is locked:

0b ... EAS mode and EAS_ID are not locked

1b ... EAS mode and EAS_ID are locked. EAS mode and EAS_ID can also be

locked with the LOCK EAS command (see Section 8.5.3.14).

Note: To avoid unauthorized change of EAS, password protect the EAS

functionality.
