DESCRIPTION
(OPTIONAL FLASH FEATURES AND COMMANDS)
Primary extended query table
Unique ASCII string, PRI
Major version number, ASCII
Minor version number, ASCII
Optional feature and command support (1 = yes, 0 = no) bits 9–31
are reserved; undefined bits are “0.” If bit 31 is “1,” then another
31-bit field of optional features follows at the end of the bit 30
field.
Bit 0 Chip erase supported = no = 0
Bit 1 Suspend erase supported = yes = 1
Bit 2 Suspend program supported = yes = 1
Bit 3 Legacy lock/unlock supported = yes = 11
Bit 4 Queued erase supported = no = 0
Bit 5 Instant Individual block locking supported = no = 0
Bit 6 Protection bits supported = yes = 1
Bit 7 Page mode read supported = yes = 1
Bit 8 Synchronous read supported = no = 0
Supported functions after suspend: read array, status, query
Other supported operations:
Bits 1–7 Reserved; undefined bits are “0”
Bit 0 Program supported after erase suspend = yes = 1
Block status register mask
Bits 2–15 Reserved; undefined bits are “0”
Bit 0 Block lock bit status register active = yes = 1
Bit 1 Block lock down bit status active = no = 0
VCC logic supply highest-performance program/erase voltage
Bits 0–3 BCD value in 100mV
Bits 4–7 BCD value in volts
VPP optimum program/erase supply voltage
Bits 0–3 BCD value in 100mV
Bits 4–7 Hex value in volts
