Cycle
1. LPC mode uses consecutive Write cycles to complete a command sequence; PP mode uses consecutive bus cycles to complete a
command sequence.
2. YYYY = A[31:16]
In LPC mode, during SDP command sequence, YYYY must be within memory address range specified in Figures 4 and 5.
In PP mode, YYYY can be V
IL
or V
IH
.
3. PA = Program Byte address
4. SAx for Sector-Erase Address
5. BAx for Block-Erase Address
6. Chip-Erase is supported in PP mode only
