Operation
20.2 Operation
The APB interface of the OCOTP provides two functions:
The OTP is divided into 32-bit words (40 in total). All of the 40 words are memory-mapped
to APBH addresses (for reads only). Writes require the use of HW_OCOTP_CTRL_ADDR.
The high-level OTP allocation for i.MX28 is shown below.

• Programmer-model access to registers (see
• Restricted 32-bit word write/program access to the 1.25 Kbit OTP.
These operations require a bank opening sequence through
HW_OCOTP_CTRL_RD_BANK_OPEN.
