Top Edge
The PICs on the top edge are different from PIOs on the left, right and bottom edges. PIOs on this edge do not
have registers or DQS signals.
The exact DQS pins are shown in a dual function in the Logic Signal Connections table in this data sheet. Addi-
tional detail is provided in the Signal Descriptions table. The DQS signal from the bus is used to strobe the DDR
data from the memory into input register blocks. Interfaces on the left and right edges are designed for DDR mem-
ories that support 16 bits of data, whereas interfaces on the bottom are designed for memories that support 18 bits
of data.
