NO_KEY_STATE=read_only
Lock configuration LSBs for page 63 (rows 0xfc0 through 0xfff). Locks are stored with 3-way majority vote encoding, so that bits can be set independently.
This OTP location is always readable, and is write-protected by its own permissions.
| KEY_W | Index 1-6 of a hardware key which must be entered to grant write access, or 0 if no such key is required. |
| KEY_R | Index 1-6 of a hardware key which must be entered to grant read access, or 0 if no such key is required. |
| NO_KEY_STATE | State when at least one key is registered for this page and no matching key has been entered. 0 (read_only): undefined 1 (inaccessible): undefined |
| RMA | Decommission for RMA of a suspected faulty device. This re-enables the factory test JTAG interface, and makes pages 3 through 61 of the OTP permanently inaccessible. |
| R1 | Redundant copy of bits 7:0 |
| R2 | Redundant copy of bits 7:0 |
