We connect FPGA to EIM of i.MX6.
We want to use a Wait(Ready) signal with an Asyncronus mode, because FPGA uses the Wait signal.
However, the EIM_WAIT signal is used only by a synchronous mode.
We understood as follows.
Is this understanding right?
- To use a wait signal with an Asyncronus mode, it is necessary to use the DTACK mode.
- A Wait signal of FPGA is connected to the EIM_DTACK_B of i.MX6.
- DTACK signal is sampled at rising edge of first ACLK after DTACK assertion.
