Dear Sir or Madam,




Refer to 6.4.1 EIM features in MCIMX6SDLRM(Rev.1).

There is following description.

External interrupt support using the RDY_INT signal function as an external interrupt pin.


Refer to Table 22-2. EIM External Signals in MCIMX6SDLRM(Rev.1).

EIM_WAIT pin multiplexed EIM_WAIT and EIM_DTACK signal.

Is RDY_INT signal muxed, too?



In case that one enable both of EIM_WAIT_B signal by RFL/WFL and RDY_INT signal by INTEN.

Does it become the following operation?

"In synchronous access, it operates as the WAIT_B signal. && Every time WAIT_B signal is asserted, the interruption occurs as the RDY_INT signal."
