hello,
i was studying about PCD8544, n then i got a question in my mind.

if we can input 8-bits at one time in the ram of PCD8544, then howcome it's possible to manage one dot i.e. one pixel on the display,

if i want to make a dot on the
x=0,y=2
pixel then i will send the data serially as
[on the address x=0,y=0]
d7 d6 d5 d4 d3 d2 d1 d0
0 0 1 0 0 0 0 0

and after that, if i want to make a dot on
x=0,y=5
pixel then i will send data serially as
[on address x=0,y=0]
d7 d6 d5 d4 d3 d2 d1 d0
0 0 0 0 0 1 0 0

i am wondering that, sending the data second time, will erase the first dot, as it will over write the ram's address
please tell me how do we deal with this type of problem, i want to print dots on the screen randomly, but i am confused that my code will delete the other dots present in the same ram address...
