AD9838 asserting reset pin/reset bit at the same time?

Hello,

 

There is a reset pin on the AD9838, which can pull the part out of reset by a negative transition (p20 of datasheet). What happens if the pin is pulled the ground by default and I assert the register bit with a micro-controller? I may have made a mistake in my PCB design, so does that mean it will never be put in the "reset" state (or only very temporarily so until the next falling edge of the MCLK).

 

Thanks.
