sir,

when i swithoff the main supply my voltage drop is very slow,

i think this because of dc filtering can i make it as it drop istantly...

Hi,

from what you describe this could be the buffer capacitors of the voltage supply. Usually they help to stabilize the DC voltage.

Best regards,

Sir,

i want to know the role of pmmcore bit

is the selection of this bit is according to main frequency or something different???

and ,

another question is about priority

as i check on datasheet the priority of UCA0RXIFG IS higher than sd24

i want to make the priority of sd24 higher than UCA0RXIFG

Hello Satish,

for the f frequencies:
f > f0, pmmcore >= 1,
f > f1, pmmcore >= 2,
f > f2, pmmcore >= 3.

Right now I have no idea how to swap SD24 and USCI priorities.
As I remember, it cannot be done.
