Follow the steps below for MTP write operation:
1. Configure all MTP registers.
2. Write PROTECT_REG (14h), bit[6] from 0 to 1. This disables write protection.
3. Ensure that the buck is off before MTP configurations. It is recommended to pull down the external
EN pin.
4. Write MTP_AUTO_REG (30h), bit[7] from 0 to 1 for MTP auto-writing.
5. Wait about 2s.
6. Read register MTP_AUTO_REG (30h). If MTP_AUTO_REG (30h) = 0x5A, then MTP configuring is
complete.
