Description

RTC secure configuration register

Fields

ALRASEC

Alarm A and SSR underflow protection

0 (B_0x0): RTC alarm A and SSR underflow configuration and interrupt clear can be written when the APB access is secure or non-secure.

1 (B_0x1): RTC alarm A and SSR underflow configuration and interrupt clear can be written only when the APB access is secure.

ALRBSEC

Alarm B protection

0 (B_0x0): RTC alarm B configuration and interrupt clear can be written when the APB access is secure or non-secure.

1 (B_0x1): RTC alarm B configuration and interrupt clear can be written only when the APB access is secure.

WUTSEC

Wake-up timer protection

0 (B_0x0): RTC wake-up timer configuration and interrupt clear can be written when the APB access is secure or non-secure.

1 (B_0x1): RTC wake-up timer configuration and interrupt clear can be written only when the APB access is secure.

TSSEC

Timestamp protection

0 (B_0x0): RTC timestamp configuration and interrupt clear can be written when the APB access is secure or non-secure.

1 (B_0x1): RTC timestamp configuration and interrupt clear can be written only when the APB access is secure.

CALSEC

Shift register, daylight saving, calibration and reference clock protection

0 (B_0x0): Shift register, daylight saving, calibration and reference clock can be written when the APB access is secure or non-secure.

1 (B_0x1): Shift register, daylight saving, calibration and reference clock can be written only when the APB access is secure.

INITSEC

Initialization protection

0 (B_0x0): RTC Initialization mode, calendar and prescalers registers can be written when the APB access is secure or non-secure.

1 (B_0x1): RTC Initialization mode, calendar and prescalers registers can be written only when the APB access is secure.

SEC

RTC global protection

0 (B_0x0): All RTC registers can be written when the APB access is secure or non-secure, except the registers protected by other secure protection bits.

1 (B_0x1): All RTC registers can be written only when the APB access is secure.
