10.3 Multiplexed Interface
With a multiplexed interface, Mobile DiskOnChip P3 requires the signals shown in Figure 19
below.
10.4 Connecting Control Signals
10.4.1 Standard Interface
When using a standard NOR-like interface, connect the control signals as follows:
•
•
•
•
•
60
A[12:0] – Connect these signals to the host’s address signals (see Section 10.8 for
platform-related considerations). Address signal A[0] is multiplexed with the DPD signal.
D[15:0] – Connect these signals to the host’s data signals (see Section 10.8 for platform-related
considerations).
Output Enable (OE#) and Write Enable (WE#) – Connect these signals to the host RD# and
WR# signals, respectively.
Chip Enable (CE#) – Connect this signal to the memory address decoder. Most RISC
processors include a programmable decoder to generate various Chip Select (CS) outputs for
different memory zones. These CS signals can be programmed to support different wait states
to accommodate Mobile DiskOnChip P3 timing specifications.
Power-On Reset In (RSTIN#) – Connect this signal to the host active-low Power-On Reset
signal.
