Hello
What is meaning of this data &= 0x0F. does it equal data = data & 0x0F ?
data = 11101111
data = 11011111
data = 10111111
data = 01111111
data &= 0x0F
data 1110 1111
Ox0F 0000 1111
result 0000 1111
What is meaning of this data &= 0x0F. does it equal data = data & 0x0F ?
Code:
data &= 0x0F;
for(i = 0; i < 4; i++)
{
data &=~( 0x80 >> i);
data |= 0x80>>i;
}
data = 11011111
data = 10111111
data = 01111111
data &= 0x0F
data 1110 1111
Ox0F 0000 1111
result 0000 1111
