title: STMicroelectronics STM32 Factory-programmed data bindings
description: |
This represents STM32 Factory-programmed read only non-volatile area: locked
flash, OTP, read-only HW regs... This contains various information such as:
analog calibration data for temperature sensor (e.g. TS_CAL1, TS_CAL2),
internal vref (VREFIN_CAL), unique device ID...
