What i mean is if that numbers corresponds to 8 LATx for example for portA

For example if we write

LATA = 5

is that number correspond to binary 8 bit LATA.x , so that number 5 will write only to %00000101 which is the LATA.0 and LATA.2

Can we write a number then to only one LATA.x

for example can we write

LATA.0 = 5

What that number will represent for the LATA.0

based on the schematic logic gates receive only 0s or 1s. So LATA.x could only get 0s or 1s. Is that right?
