AttachInterruptPin.h

/* AttachInterruptPin v1.0, 04/04/2022, toranlo
 
 AttachInterrupt for all pins of Arduino Uno, Nano, Mini and other 328-based
 boards. The Arduino attachInterrupt() function only allows pines 2 & ~3.
 Interrupt is trigered by a pin change status (rising or falling edge).
 One or more pins can be combined to activate the same interrupt
 PCINT0 (higher priority): Arduino Uno pins 13,12,~11,~10,~9,8.
 PCINT1                  : Arduino Uno pins A5,A4,A3,A2,A1,A0.
 PCINT2 (lower priority) : Arduino Uno pins 7,~6,~5,4,~3,2,1TX,0RX.
