Subject: [AVR-Chat] How to handle PCINT8-11 on ATMEGA644P


Hello!
 build project on AVRStudio 4.16 and WinAVR.
 try handle  high level on PCINT8-11.
PORTB=0x00;
DRB=0xF0;
EICRA=0x02;
IMSK=0x01;
IFR=0x01;
CMSK1=0x0F;
CICR=0x02;
CIFR=0x02;
ISR(PCINT1_vect)

 unsigned char x = PORTB;
 if ((x & Bit(0)) == 1)
 {
    ...
 }
 if ((x & Bit(1)) == 1)
 {
   ...
 }
 if ((x & Bit(2)) == 1)
 {
   ...
 }
 if ((x & Bit(3)) == 0)
 {
    ...
 }

It doesn't work.
