Interval = 500µs Erase resume to suspend interval =(count+1)*64µs A23:A20= 7 =0111b 5FH A30:A24 38H Suspend in-progress erase max latency Maximum time required by the flash device to suspend an in-progress erase and be ready to accept another command which accesses the flash array. Max latency = 25µs Erase max latency =(count+1)*units units (00b:128ns, 01b:1µs, 10b:8µs, 11b:64µs) A28:A24= count = 24 = 11000b A30:A29 = 1µs =01b A31 Suspend/Resume supported 0:supported 1:not supported JEDEC Flash Parameter Table: 13th DWORD 60H A7:A0 30H Program Resume Instruction 61H A15:A8 B0H Program Suspend Instruction 62H A23:A16 30H Resume Instruction 63H A31:A24 B0H Suspend Instruction JEDEC Flash Parameter Table: 14th DWORD 64H A1:A0 F7H Reserved = 11b A7:A2 Status Register Polling Device Busy 111101b: Use of legacy polling is supported by reading the status register with 05h instruction and checking WIP bit [0] (0=ready, 1=busy) 65H A14:A8 FFH Exit Deep Power-down to next operation delay A15 Exit Power-down Instruction 66H A22:A16 FFH Enter Power-down instruction A23 67H A30:A24 FFH Deep Power-down Supported 0:supported 1:not supported A31 JEDEC Flash Parameter Table: 15th DWORD 68H A3:A0 29H 4-4-4 mode disable sequences Xxx1b: issue FF instruction 1xxxb: issue the Soft Reset 66/99 sequence.
