Detailed Description

TSN factory-calibration block (read-only on hardware).

HUM Ch 55.2.2 "TSCDR / TSCDR2 : Temperature Sensor Calibration Data Registers", p 3498-3499. The two words are programmed at the factory and capture the raw ADC code observed at the high and low calibration temperatures (HUM Ch 55.3.1 p 3499-3500):

• TSCDR – code at the high reference (105 or 125 degC).
• TSCDR2 – code at the low reference (-40 degC).

Both words are 32-bit memory cells in the MRAM trim area but only the lower 12 bits (k_ra8_tscdr_data_mask) carry the calibration code; the upper bits read 0.

Note

The cells live in the MRAM trim region (0x02C1EDA0). Hardware exposes them as read-only; tests inject values by writing to the fake mmap backing store.
