Enumeration Type Documentation

BlockProtect

enum class at25040::BlockProtect : uint8_t

strong

Block write protection level, BP1:BP0 in the status register (datasheet Table 6-4).

Addresses for the AT25040B; on the AT25010B/020B the same levels protect the same fractions.

Enumerator
None	BP1:BP0 = 00: nothing protected.
UpperQuarter	01: 0x180-0x1FF read-only
UpperHalf	10: 0x100-0x1FF read-only
All	11: 0x000-0x1FF read-only
