SNVS_HP Status Register
| HPTA | HP Time Alarm Indicates that the HP Time Alarm has occurred since this bit was last cleared. 0 (NOREPORT): No time alarm interrupt occurred. 1 (REPORTED): A time alarm interrupt occurred. |
| PI | Periodic Interrupt Indicates that periodic interrupt has occurred since this bit was last cleared. 0 (NOREPORT): No periodic interrupt occurred. 1 (REPORTED): A periodic interrupt occurred. |
| LPDIS | Low Power Disable If 1, the low power section has been disabled by means of an input signal to SNVS |
| BTN | Button Value of the BTN input |
| BI | Button Interrupt Signal ipi_snvs_btn_int_b was asserted. |
| SSM_STATE | System Security Monitor State This field contains the encoded state of the SSM’s state machine 0 (INIT): Init 1 (HARD_FAIL): Hard Fail 3 (SOFT_FAIL): Soft Fail 8 (INTERMEDIATE): Init Intermediate (transition state between Init and Check - SSM stays in this state only one clock cycle) 9 (CHECK): Check 11 (NON_SECURE): Non-Secure 13 (TRUSTED): Trusted 15 (SECURE): Secure |
| SYS_SECURITY_CFG | System Security Configuration This field reflects the three security configuration inputs to SNVS 0 (FAB_CONFIG): Fab Configuration - the default configuration of newly fabricated chips 1 (OPEN_CONFIG): Open Configuration - the configuration after NXP-programmable fuses have been blown 3 (CLOSED_CONFIG): Closed Configuration - the configuration after OEM-programmable fuses have been blown 7 (FIELD_RETURN_CONFIG): Field Return Configuration - the configuration of chips that are returned to NXP for analysis |
| SYS_SECURE_BOOT | System Secure Boot If SYS_SECURE_BOOT is 1, the chip boots from internal ROM |
| OTPMK_SYNDROME | One Time Programmable Master Key Syndrome In the case of a single-bit error, the eight lower bits of this value indicate the bit number of error location |
| OTPMK_ZERO | One Time Programmable Master Key is Equal to Zero 0 (OTPMK_NOT_ZERO): The OTPMK is not zero. 1 (OTPMK_IS_ZERO): The OTPMK is zero. |
| ZMK_ZERO | Zeroizable Master Key is Equal to Zero 0 (ZMK_NOT_ZERO): The ZMK is not zero. 1 (ZMK_IS_ZERO): The ZMK is zero. |
