TABLE1. SOFTWARE COMMAND DEFINITIONS
Note:
1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacture code,A1=0, A0 = 1 for device code.
(Refer to Table 3)
DDI = Data of Device identifier : C2H for manufacture code, ADH for device code.
X = X can be VIL or VIH
RA=Address of memory location to be read.
RD=Data to be read at location RA.
2.PA = Address of memory location to be programmed.
PD = Data to be programmed at location PA.
SA = Address of the sector to be erased.
SGA = Address of the Sector Group Address bits A18-A20 select a uniqul sector group.
3.The system should generate the following address patterns: 555H or 2AAH to Address A10~A0 .
Address bit A11~A20=X=Don't care for all address commands except for Program Address (PA) and Sector
Address (SA). Write Sequence may be initiated with A11~A20 in either state.
4.For Sector Group Protect Verify Operation : If read out data is 01H, it means the sector has been protected.If read
out data is 00H,it means the sector is still not being protected.
COMMAND DEFINITIONS
Device operations are selected by writing specific address
and data sequences into the command register. Writing
incorrect address and data values or writing them in the
improper sequence will reset the device to the read mode.
Table 1 defines the valid register command sequences.
Note that the Erase Suspend (B0H) and Erase Resume
(30H) commands are valid only while the Sector Erase
operation is in progress.
