TS_CAL1

TS ADC raw data acquired at temperature of

30 °C ±5 °C

VDDA = VREF+ = 3.3 V ±10 mV

0x5C00 525C[15:0](1)(2)

1. It is mandatory to read a 32-bit word and to do relevant masking and shifting to isolate the required bits.

2. This address is located inside the BSEC and the access is allowed after being enabled in the RCC.
