Notes:
1. Address Format: A14
A0 (Hex); Data Format: DQ7-DQ0 (Hex)
2. Either one of the two Product ID Exit commands can be used.
3. SA means: Sector Address
If SA is within 3C000 to 3FFFF (Boot Block address range), and the Boot Block programming lockout feature is activated,
nothing will happen and the device will go back to read mode after 100nS.
If the Boot Block programming lockout feature is not activated, this command will erase Boot Block.
If SA is within 3A000 to 3BFFF (Parameter Block1 address range), this command will erase PB1.
If SA is within 38000 to 39FFF (Parameter Block2 address range), this command will erase PB2.
If SA is within 20000 to 37FFF (Main Memory Block1 address range), this command will erase MMB1.
If SA is within 00000 to 1FFFF (Main Memory Block2 address range), this command will erase MMB2.
