Register block

Fields

host_cryptokey_sel: Reg<HOST_CRYPTOKEY_SEL_SPEC>

0x1a38 - AES hardware key select

host_iot_kprtl_lock: Reg<HOST_IOT_KPRTL_LOCK_SPEC>

0x1a4c - This write-once register is the K_PRTL lock register. When this register is set, K_PRTL can not be used and a zeroed key will be used instead. The value of this register is saved in the CRYPTOCELL AO power domain.

host_iot_kdr0: Reg<HOST_IOT_KDR0_SPEC>

0x1a50 - This register holds bits 31:0 of K_DR. The value of this register is saved in the CRYPTOCELL AO power domain. Reading from this address returns the K_DR valid status indicating if K_DR is successfully retained.

host_iot_kdr1: Reg<HOST_IOT_KDR1_SPEC>

0x1a54 - This register holds bits 63:32 of K_DR. The value of this register is saved in the CRYPTOCELL AO power domain.

host_iot_kdr2: Reg<HOST_IOT_KDR2_SPEC>

0x1a58 - This register holds bits 95:64 of K_DR. The value of this register is saved in the CRYPTOCELL AO power domain.

host_iot_kdr3: Reg<HOST_IOT_KDR3_SPEC>

0x1a5c - This register holds bits 127:96 of K_DR. The value of this register is saved in the CRYPTOCELL AO power domain.

host_iot_lcs: Reg<HOST_IOT_LCS_SPEC>

0x1a60 - Controls lifecycle state (LCS) for CRYPTOCELL subsystem
