Specification - Chapter 7 (version 2.0).
CAN (controller area network) interface
Refer to I/O port characteristics for more details on the input/output alternate function char-
acteristics (CANTX and CANRX).
12-bit ADC characteristics
Unless otherwise specified, the parameters given in Table 39 are derived from tests
performed under ambient temperature, fPCLK2 frequency and VDDA supply voltage
conditions summarized in Table 7.
It is recommended to perform a calibration after each power-up.
