1.2.16.2 ACM Bus Part of Init/CFG Interface

Selecting this option creates your own multiplexors between the Init/CFG interface and your user logic. The INIT_DONE signal from the Flash Memory System can be used to indicate when the Init/CFG operation is complete. This signal should be used to select the MUX.

The following ports are related to this interface:


Port Name	Input/Output	Description
ACMCLK	Input	Clock for ACM interface. The max frequency for this clock is 10 MHz; it must be the same frequency that is used during Initialization from the Flash Memory System.
ACMRDATA_I[7:0]	Output	Data read from the ACM.
INIT_ADDR[7:0]	Input	The ACM bus is shared with the Initialization interface of the Flash Memory System. This port is always exposed; the address of the ACM uses this port as part of the Initialization interface. You must multiplex your ACM address with the Initialization address into this port. The selection of the multiplexer can be based on the INIT_DONE from the Flash Memory System.
INIT_DATA[7:0]	Input	The ACM bus is shared with the Initialization interface of the Flash Memory System. This port is always exposed; the data written into the ACM uses this port as part of the Initialization interface. You must multiplex your ACM write data with the Initialization data into this port. The selection of the multiplexer can be based on the INIT_DONE from the Flash Memory System.
INIT_ACM_WEN	Input	The ACM bus is shared with the Initialization interface of the Flash Memory System. This port is always exposed; the data write enable of the ACM uses this port as part of the Initialization interface. You must multiplex your ACM write enable with the Initialization write enable into this port. The selection of the multiplexer can be based on the INIT_DONE from the Flash Memory System.
