20.4.20 Value of OTP Bank2 Word1 (Freescale OPS0)
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.
Shadowed memory mapped access to OTP Bank 2, word 1 (ADDR = 0x11).

Status of HW/SW Capability shadow register lock. When set, over-ride of HW/SW capabality shadow bits
is blocked.
Status of read lock bit for DCP APB crypto access. When set, the DCP will disallow reads of its crypto keys
through its APB interface.
Status of crypto key region (ADDR = 0x04-0x07) read/write lock bit. When set, region is locked.
Status of customer region word (ADDR = 0x03) write lock bit. When set, the region is locked.
Status of customer region word (ADDR = 0x02) write lock bit. When set, the region is locked.
Status of customer region word (ADDR = 0x01) write lock bit. When set, the region is locked.
Status of customer region word (ADDR = 0x00) write lock bit. When set, the region is locked.
Reflects value of OTP Bank 2, word 1 (ADDR = 0x11)
