EIM_ACLK_FREERUN signal of the EIM interface in iMX7 processor

Hello,

Our client has the following question about eim_aclk_freerun signal of the  EIM interface in iMX7 processor:

" there is a signal eim_aclk_freerun signal which is a input signal to CPU module,my question is Must I connect this port to a freerun clock when I enable EIM interface? Could you give us some advice on how to handle this signal?"

In i.MX7 Reference manual and datasheet I only found that it's AXI clock signal (table 9-25, sec.9.7.2 in the Reference manual).
I would like to receive more details information about this signal and its necessity for the EIM interface.

Thank You,

Boris

Hello,

 

  EIM_ACLK_FREERUN  was designed to support continuous clock for synchronization

with an external device, if needed. Generally this signal is not required for EIM functioning.  

  Some  details may be found in the following discussion regarding i.MX6:

   i.MX6 Continuous BCLK 

 

Have a great day,

Yuri
