1. LPC mode use consecutive Write cycles to complete a command sequence; PP mode use consecutive bus cycles to complete a
command sequence.
2. YYYY = A[31:16]. In LPC mode, during SDP command sequence, YYYY must be within valid memory address range, see Address
out of range section for details. In PP mode, YYYY can be V
IL
or V
IH
, but no other value.
3. PA = Program Byte address
