The Device configuration register is a user programmable OTP register which contains device configuration information. This
The DEVCFG[7] bit is unused. Writes to DEVCFG[7] will be ignored. Reads of DEVCFG[7] will always return ‘1’.
The User Configuration CRC bits contain the 3-bit CRC used for verification of the user programmable OTP array. Reference
The Device configuration register is a user programmable OTP register which contains device configuration information. This
The User Specific Data bits have no impact on the device function or performance. The bits can be programmed with user or
The Attribute Bits are user defined bits which are transmitted in response to the Request Status, Disable Self-Test Stimulus or
