Programmable Registers
20.4.10 Value of OTP Bank0 Word7 (Crypto Key)
OTP banks must be open through HW_OCOTP_CTRL[RD_BANK_OPEN] before reading
this register. Reading this register without having HW_OCOTP_CTRL[RD_BANK_OPEN]
set and HW_OCOTP_CTRL[BUSY] clear, will result in HW_OCOTP_CTRL[ERROR]
being set and 0xBADA_BADA being returned.
Non-shadowed memory mapped access to OTP Bank 0, word 7 (ADDR = 0x07).
Address:
Re-
20.4.11 HW Capability Shadow Register 0 (HW_OCOTP_HWCAP0)
Copied from the OTP automatically after reset. Can be re-loaded by setting
HW_OCOTP_CTRL[RELOAD_SHADOWS]
Shadowed memory mapped access to OTP bank 1, word 0 (ADDR = 0x08).

Reflects value of OTP Bank 0, word 7 (ADDR = 0x07). If HW_OCOTP_LOCK[CRYPTOKEY] is set, returns
0xBADA_BADA and sets HW_OCOTP_CTRL[ERROR]
Shadow register for HW capability bits 31:0 (copy of OTP bank 1, word 0 (ADDR = 0x08)). These bits become
read-only after the HW_OCOTP_LOCK[HWSW_SHADOW] or HW_OCOTP_LOCK[HWSW_SHADOW_ALT]
bit is set.
