SNVS_LP Lock Register
| ZMK_WHL | Zeroizable Master Key Write Hard Lock When set, prevents any writes (software and hardware) to the ZMK registers and ZMK_HWP, ZMK_VAL, and ZMK_ECC_EN fields of the LPMKCR 0 (ZMK_WHL_0): Write access is allowed. 1 (ZMK_WHL_1): Write access is not allowed. |
| ZMK_RHL | Zeroizable Master Key Read Hard Lock When set, prevents any software reads to the ZMK registers and ZMK_ECC_VALUE field of the LPMKCR 0 (ZMK_RHL_0): Read access is allowed (only in software programming mode). 1 (ZMK_RHL_1): Read access is not allowed. |
| SRTC_HL | Secure Real Time Counter Hard Lock When set, prevents any writes to the SRTC registers, SRTC_ENV, and SRTC_INV_EN bits 0 (SRTC_HL_0): Write access is allowed. 1 (SRTC_HL_1): Write access is not allowed. |
| LPCALB_HL | LP Calibration Hard Lock When set, prevents any writes to the LP Calibration Value (LPCALB_VAL) and LP Calibration Enable (LPCALB_EN) 0 (LPCALB_HL_0): Write access is allowed. 1 (LPCALB_HL_1): Write access is not allowed. |
| MC_HL | Monotonic Counter Hard Lock When set, prevents any writes (increments) to the MC Registers and MC_ENV bit 0 (MC_HL_0): Write access (increment) is allowed. 1 (MC_HL_1): Write access (increment) is not allowed. |
| GPR_HL | General Purpose Register Hard Lock When set, prevents any writes to the GPR 0 (GPR_HL_0): Write access is allowed. 1 (GPR_HL_1): Write access is not allowed. |
| LPSVCR_HL | LP Security Violation Control Register Hard Lock When set, prevents any writes to the LPSVCR 0 (LPSVCR_HL_0): Write access is allowed. 1 (LPSVCR_HL_1): Write access is not allowed. |
| LPTDCR_HL | LP Tamper Detectors Configuration Register Hard Lock When set, prevents any writes to the LPTDCR 0 (LPTDCR_HL_0): Write access is allowed. 1 (LPTDCR_HL_1): Write access is not allowed. |
| MKS_HL | Master Key Select Hard Lock When set, prevents any writes to the MASTER_KEY_SEL field of the LP Master Key Control Register 0 (MKS_HL_0): Write access is allowed. 1 (MKS_HL_1): Write access is not allowed. |
