Programmable Registers
20.4.2 OTP Controller Write Data Register (HW_OCOTP_DATA)
The OCOTP Data Register is used for OTP Programming
This register is used in conjunction with HW_OCOTP_CTRL to perform one-time writes
to the OTP. See the
Address:
Re-
20.4.3 Value of OTP Bank0 Word0 (Customer) (HW_OCOTP_CUST0)
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 0 (ADDR = 0x00).
