Device configuration register 2 is a user programmable OTP register which contains device configuration information. This
The LOCK_U bit is a factory or user programmed OTP bit which inhibits writes to the user configuration array when active.
The PCM Bit enables the PCM output pin. When the PCM bit is set, the PCM output pin is active and outputs a Pulse Code
The Device Address bits define the preprogrammed DSI Bus device address. If the Device Address bits are programmed to
The User Data Registers are user programmable OTP register which can be programmed with user or assembly specific in-
