Extended Query table contents for Primary Algorithm. Address (P+5)h
contains less significant byte.
bit 0Chip Erase supported(1 = Yes, 0 = No)
bit 1Suspend Erase supported(1 = Yes, 0 = No)
bit 2Suspend Program supported(1 = Yes, 0 = No)
bit 3Legacy Lock/Unlock supported(1 = Yes, 0 = No)
bit 4Queued Erase supported(1 = Yes, 0 = No)
bit 5Instant individual block locking supported(1 = Yes, 0 = No)
bit 6Protection bits supported(1 = Yes, 0 = No)
bit 7Page mode read supported(1 = Yes, 0 = No)
bit 8Synchronous read supported(1 = Yes, 0 = No)
bit 31 to 9Reserved; undefined bits are ‘0’
Supported Functions after Suspend
Read Array, Read Status Register and CFI Query are always supported
during Erase or Program operation
bit 0Program supported after Erase Suspend (1 = Yes, 0 = No)
bit 7 to 1Reserved; undefined bits are ‘0’
Block Lock Status
Defines which bits in the Block Status Register section of the Query are
implemented.
Address (P+A)h contains less significant byte
