1. Only the Read command structures are different between the 'Continuous Read Mode (BUF=0)' and the 'Buffer Read Mode (BUF=1)', all other commands are identical W35N01JWxxxG: Default BUF=1 after power up W35N01JWxxxT: Default BUF=0 after power up
2. LUT stands for Look-Up Table
3. OTP pages can only be programmed
