Table 11: Software Data Protection Command Definition
Notes:
1.
LPC Mode uses consecutive Write cycles to complete a command sequence; A/A Mux Mode uses consecutive bus cycles to complete a
command sequence.
YYYY = A[31:16]. In LPC mode, during SDP command sequence, YYYY must be within memory address range specified in Table 5. In A/A
Mux mode, YYYY can be V
IL
or V
IH
, but no other value.
Chip erase is available in A/A Mux Mode only.
BA: Block Erase Address.
Either 30H or 50H are acceptable for Block Erase.
PA: Program Byte Address; PD: Byte data to be programmed.
Both Product ID Exit commands are equivalent.
