Motor-Control I/O Interface; Table 64. Motor-Control Terminal And I/O Function Assignment - ST STM32U575I-EV User Manual

7.33.2 Motor‑control I/O interface
The motor‑control I/O interface is not connected by default, because it is too high I/O consuming.
Table 64 describes the assignment of the motor‑control interface and the I/O function associated with
STM32U575AII6Q.
