simple code problem

[neelam29]

Hi,
last night i was trying to interface ADE7754 with 89c51. I just gave 220 v AC voltage at Phase A input (via 1Mohm/1K resistor network) and read the value of AVrms register which is showing a huge value which changes with change in voltage. But the value is too large than maximum possible.

I doubt in one part of my code. Should the code be written as :-

CLR C
SETB SCLK
CLR SCLK ;SERIAL CLOCK TO ADE7754

MOV C, DOUT ;DOUT IS DATA OUT OF ADE7754
RLC A


or should this be as below????

CLR C
SETB SCLK

MOV C, DOUT
RLC A

CLR SCLK ;CLR SCLK SHOULD BE DONE AFTER RLC?????

Thanks
