H / 01 type is “VI/O = Vcc = 2.7 ~ 3.6V, highest address sector protected.”
L / 02 type is “VI/O = Vcc = 2.7 ~ 3.6V, lowest address sector protected.”
2. Macronix ‘U/D’ is same as Spansion ‘V1/V2’ definition. Macronix: 128Mb~256Mb; Spansion: 128Mb~1Gb
U / V1 type is “VI/O = 1.65 ~ Vcc, Vcc = 2.7 ~ 3.6V, highest address sector protected.”
D / V2 type is “VI/O = 1.65 ~ Vcc, Vcc = 2.7 ~ 3.6V, lowest address sector protected.”
3. Solid Protection is same function as Persistent Protection, which is just different naming.
