Question about OTP of LPC54605J512

I am using LPC54605J512 and trying to read/write OTP. I can read/write Banks 0 and 3 with no problems. However, I cannot write Banks 1 and 2. When I execute OTP_ProgramRegister() to Bank 1 or 2, it returns the error code of “illegal bank.” Do I have to use different API to write Banks 1 and 2? Or, simply the LPC54605J512 has Banks 0 and 3 only?
