This bit enables or disables the pullup/interrupt on port B, bit 7. 1 = Enables the pullup/interrupt
0 = Disables the pullup/interrupt
PB6PU — Port B6 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 6. 1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
PB5PU — Port B5 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 5. 1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
PB4PU — Port B4 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 4. 1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
