RTC secure configuration register
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. |
