What is the difference between static lock bytes and dynamic lock byte

Hi,

 

Taking NTAG 216 for example, I understood that static lock bytes are OTP bytes. While, for dynamic lock bytes, through my experiment, I found  that  I cannot change them back to 0 either. But this is not mentioned in the spec  http://www.nxp.com/documents/data_sheet/NTAG213_215_216.pdf .  So just wanted to confirm:

 

1. Are dynamic lock bytes also OTP bytes? Or is there a way to change them back to 0 once they are set to 1?

2. If dynamic lock bytes also OTP bytes, then what is the difference between static and dynamic lock bytes except that they lock different address. Basically I don't understand the meaning of  'static' and 'dynamic'.

 

Thanks!
