Table 5.
The Command Interface only uses A–1, A0-A10 and DQ0-DQ7 to verify the commands;
A11-A17, DQ8-DQ14 and DQ15 are Don’t Care. DQ15A–1 is A–1 when BYTE is V
IL
or
DQ15 when BYTE is V
IH
.
4.11
Read/Reset
After a Read/Reset command, read the memory as normal until another command is
issued.
4.12
Auto Select
After an Auto Select command, read Manufacturer ID, Device ID or Block Protection Status.
4.13
Program, Unlock Bypass Program, Chip Erase, Block Erase
After these commands read the Status Register until the Program/Erase Controller
completes and the memory returns to Read Mode. Add additional Blocks during Block
Erase Command with additional Bus Write Operations until Timeout Bit is set.
Commands, 8-bit mode, BYTE = V
IL(1) (2)
1.
X = Don’t Care, PA = Program Address, PD = Program Data, BA = Any address in the Block.
2.
All values are in hexadecimal.
