LS1043A IFC clock generation during power-on-reset

[michael_machesk]

Hi,

Question on the generation of clock outputs by the LS1043A processor during the power-on-reset sequence.  While PORESET_B is being held asserted to the LS1043A will the processor generate a clock output on IFC_CLK?  Or does PORESET_B need to be deasserted first for the LS1043A to start generating a clock output on IFC_CLK?

Thanks,

Mike
