Notes:
1. Addresses are A19:A0 in word mode (BYTE#=V_IH) , A19:A-1 in byte mode (BYTE#=V_IL).
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the “Sector Pro-
tection and Unprotection” section.
3. D_IN or D_OUT as required by command sequence, data polling, or sector protection algorithm.
