Address (P+5)h contains less significant byte. bit 0 Chip Erase supported (1 = Yes, 0 = No) bit 1 Erase Suspend supported (1 = Yes, 0 = No) bit 2 Program Suspend supported (1 = Yes, 0 = No) bit 3 Legacy Lock/Unlock supported (1 = Yes, 0 = No) bit 4 Queued Erase supported (1 = Yes, 0 = No) bit 5 Instant individual block locking supported (1 = Yes, 0 = No) bit 6 Protection bits supported (1 = Yes, 0 = No) bit 7 Page mode read supported (1 = Yes, 0 = No) bit 8 Synchronous read supported (1 = Yes, 0 = No) bit 9 Simultaneous operation supported (1 = Yes, 0 = No) bit 10 to 31 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.
