2.1.16.1 ACM Bus Independent

When this option is selected, the Analog System Builder instantiates an internal multiplexer that arbitrates access between the INIT/CFG interface and user logic for the Analog Configuration multiplexer (ACM) bus.

This option is recommended when direct user access to the ACM is required. The ports exposed when selecting this option are listed in the following table.

Table 2-11. ACM Bus Independent Interface Signals
Port Name	Direction	Description
ACMSCLK	Input	Clock input for the ACM interface. The maximum supported frequency is 10 MHz. This clock must operate at the same frequency used during initialization by the Flash Memory System.
ACMRDATA_I[7:0]	Output	Data read from the ACM.
ACMADDR[7:0]	Input	Address bus for accessing ACM registers.
ACMWDATA[7:0]	Input	Write‑data bus for ACM register access.
ACMWEN	Input	Write‑enable signal for ACM register writes.
