Table 14: Software Data Protection Command Definition
Notes:
1. Chip erase is available in A/A Mux Mode only.
2. Address A[15:0] is used for SDP command decoding internally and A15 must be “0” in FWH/LPC and A/A Mux modes.
AMS - A16 = Don’t care where AMS is the most-significant address of A49FL004.
3. SA = Sector address to be erased.
4. BA = Block address to be erased.
5. Either one of the Product ID Exit command can be used.
