STSPIN32G4 standby mode issue

[secupol]

I am testing the Standby mode with the EVSPIN32G4 board. However, it is not entering standby mode. When I check the Vcc voltage, it outputs 8V despite being set to standby mode. Have you checked if a functional test for standby mode has been conducted? Please check if there is an error with the STSPIN32G4 chip itself.

STSPIN32G4_init(&HdlSTSPING4);

STSPIN32G4_reset(&HdlSTSPING4);

STSPIN32G4_clearFaults(&HdlSTSPING4);

STSPIN32G4_standby(&HdlSTSPING4, true);
