Dear Sir or Madam,
Hello.
[Q1]
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?
[Q2]
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."

Solved! Go to Solution.
RDY_INT function is assigned to the EIM_WAIT pin. Generally it is assumed that corresponding functionality
of the pin (DTACK, WAIT, INT (interrupt)) is selected via EIM register settings (sync / async mode, interrupt_enable ).
If the INTEN bit is set and the signal is asserted an interrupt will be generated.
